I2C(R) CMOS 8 x 8 Unbuffered Analog Switch Array with Dual/Single Supplies ADG2188
FEATURES
I2C-compatible interface 3.4 MHz high speed I2C option 32-lead LFCSP_VQ (5 mm x 5 mm) Double-buffered input logic Simultaneous update of multiple switches Up to 300 MHz bandwidth Fully specified at dual 5 V/single +12 V operation On resistance 35 maximum Low quiescent current < 20 A
GENERAL DESCRIPTION
The ADG2188 is an analog cross point switch with an array size of 8 x 8. The switch array is arranged so that there are eight columns by eight rows, for a total of 64 switch channels. The array is bidirectional, and the rows and columns can be configured as either inputs or outputs. Each of the 64 switches can be addressed and configured through the I2C-compatible interface. Standard, full speed, and high speed (3.4 MHz) I2C interfaces are supported. Any simultaneous switch combination is allowed. An additional feature of the ADG2188 is that switches can be updated simultaneously, using the LDSW command. In addition, a RESET option allows all of the switch channels to be reset/off. At power on, all switches are in the off condition. The device is packaged in a 32-lead, 5 mm x 5 mm LFCSP_VQ.
APPLICATIONS
AV switching in TV Automotive infotainment AV receivers CCTV Ultrasound applications KVM switching Telecom applications Test equipment/instrumentation PBX systems

ADG2188 THEORY OF OPERATION
The ADG2188 is an analog cross point switch with an array size of 8 x 8. The eight rows are referred to as the X input/output lines, and the eight columns are referred to as the Y input/output lines. The device is fully flexible in that it connects any X line or number of X lines with any Y line when turned on. Similarly, it connects any X line with any number of Y lines when turned on. Control of the ADG2188 is carried out via an I2C interface. The device can be operated from single supplies of up to 13.2 V or from dual 5 V supplies. The ADG2188 has many attractive features, such as the ability to reset all the switches, the ability to update many switches at the same time, and the option of reading back the status of any switch. All of these features are described in more detail here in the Theory of Operation section.
LOAD SWITCH (LDSW)
LDSW is an active high command that allows a number of switches to be simultaneously updated. This is useful in applications where it is important to have synchronous transmission of signals. There are two LDSW modes: the transparent mode and the latched mode. Transparent Mode In this mode, the switch position changes after the new word is written into the input shift register. LDSW is set to 1. Latched Mode In this mode, the switch positions are not updated at the same time that the input registers are written to. This is achieved by setting LDSW to 0 for each word (apart from the last word) written to the device. Then, setting LDSW to 1 for the last word allows all of the switches in that sequence to be simultaneously updated.
RESET/POWER-ON RESET
The ADG2188 offers the ability to reset all of the 64 switches to the off state. This is done through the RESET pin. When the RESET pin is low, all switches are open (off), and appropriate registers are cleared. Note that the ADG2188 also has a poweron reset block. This ensures that all switches are in the off condition at power-up of the device. In addition, all internal registers are filled with 0s and remain so until a valid write to the ADG2188 takes place.
READBACK
Readback of the switch array conditions is also offered when in standard mode and fast mode. Readback enables the user to check the status of the switches of the ADG2188. This is very useful when debugging a system.
Rev. 0 | Page 18 of 28
ADG2188 SERIAL INTERFACE
The ADG2188 is controlled via an I2C-compatible serial bus. The parts are connected to this bus as a slave device (no clock is generated by the switch). 2. The peripheral whose address corresponds to the transmitted address responds by pulling the SDA line low during the ninth clock pulse, known as the acknowledge bit. At this stage, all other devices on the bus remain idle while the selected device waits for data to be written to or read from its serial register. If the R/W bit is 1 (high), the master reads from the slave device. If the R/W bit is 0 (low), the master writes to the slave device. Data is transmitted over the serial bus in sequences of nine clock pulses: eight data bits followed by an acknowledge bit from the receiver of the data. Transitions on the SDA line must occur during the low period of the clock signal, SCL, and remain stable during the high period of SCL, because a low-to-high transition when the clock is high can be interpreted as a stop signal. When all data bits have been read or written, a stop condition is established by the master. A stop condition is defined as a low-to-high transition on the SDA line while SCL is high. In write mode, the master pulls the SDA line high during the 10th clock pulse to establish a stop condition. In read mode, the master issues a no acknowledge for the ninth clock pulse (that is, the SDA line remains high). The master then brings the SDA line low before the 10th clock pulse and then high during the 10th clock pulse to establish a stop condition.
HIGH SPEED I2C INTERFACE
In addition to standard and full speed I2C, the ADG2188 also supports the high speed (3.4 MHz) I2C interface. Only the -HS models provide this added performance. See the Ordering Guide for details.
SERIAL BUS ADDRESS
The ADG2188 has a 7-bit slave address. The four MSBs are hard coded to 1110, and the three LSBs are determined by the state of Pin A0, Pin A1, and Pin A2. By offering the facility to hardware configure Pin A0, Pin A1, and Pin A2, up to eight of these devices can be connected to a single serial bus. The 2-wire serial bus protocol operates as follows: 1. The master initiates data transfer by establishing a start condition, defined as when a high-to-low transition on the SDA line occurs while SCL is high. This indicates that an address/data stream follows. All slave peripherals connected to the serial bus respond to the start condition and shift in the next eight bits, consisting of a 7-bit address (MSB first) plus an R/W bit that determines the direction of the data transfer, that is, whether data is written to or read from the slave device.

ADG2188 WRITING TO THE ADG2188
INPUT SHIFT REGISTER
The input shift register is 24 bits wide. A 3-byte write is necessary when writing to this register and is done under the control of the serial clock input, SCL. The contents of the three bytes of the input shift register are shown in Figure 33 and described in Table 6.

The LSBs of the address byte are set by the state of the three address pins, Pin A0, Pin A1, and Pin A2. Controls whether the ADG2188 slave device is read from or written to. If R/W = 1, the ADG2188 is being read from. If R/W = 0, the ADG2188 is being written to. Controls whether the switch is to be open (off ) or closed (on). If Data = 0, the switch is open/off. If Data = 1, the switch is closed/on. Controls I/Os X0 to X7. See Table 7 for the decode truth table. Controls I/Os Y0 to Y7. See Table 7 for the decode truth table. Don't care. This bit is useful when a number of switches need to be updated simultaneously. If LDSW = 1, the switch position changes after the new word is read in. If LDSW = 0, the input data is latched, but the switch position is not changed.

ADG2188
WRITE OPERATION
When writing to the ADG2188, the user must begin with an address byte and R/W bit, after which the switch acknowledges that it is prepared to receive data by pulling SDA low. This address byte is followed by the two 8-bit words. The write operations for the switch array are shown in Figure 34. Note that it is only the condition of the switch corresponding to the bits in the data bytes that changes state. All other switches retain their previous condition. b. Enter the readback address for the X line of interest, the addresses of which are shown in Table 8. Note that the ADG2188 is expecting a 2-byte write; therefore, be sure to also enter another byte of don't cares (see Figure 35). The ADG2188 then places the status of those eight switches in a register than can be read back.
c. 2.
READ OPERATION
Readback on the ADG2188 is designed to work as a tool for debug and can be used to output the status of any of the 64 switches of the device. The readback function is a two-step sequence that works as follows: 1. Select the relevant X line to be read back from. Note that there are eight switches connecting that X line to the eight Y lines. The next step involves writing to the ADG2188 to tell the part to reveal the status of those eight switches. a. Enter the I2C address of the ADG2188, and set the R/W to 0 to indicate a write to the device.
The second step involves reading back from the register that holds the status of the eight switches associated with the X line of choice. a. As before, enter the I2C address of the ADG2188. This time, set the R/W to 1 to indicate a read back from the device. As with a write to the device, the ADG2188 outputs a 2-byte sequence during readback. Therefore, the first eight bits of data out that are read back are all 0s. The next eight bits of data that come back are the status of the eight Y lines attached to that particular X line. If the bit is a 1, then the switch is closed (on); similarly, if the bit is a 0, the switch is open (off).
