0.5, Quad SPDT Switches in UCSP/QFN
General Description
The MAX4754/MAX4755/MAX4756 low on-resistance, analog switches operate from a single +1.8V to +5.5V supply. The MAX4754 and MAX4755 are dual, doublepole, double-throw (DPDT) switches. The MAX4756 is a quad, single-pole double-throw (SPDT) switch. They are configured to route either audio or data signals. The MAX4754 has four 0.5 SPDT switches for audiosignal routing and two logic control inputs. The MAX4755 has four 0.5 SPDT switches (with two switches that have an additional 11 series resistor at the NC terminals). This allows users to drive an 8 speaker as a 32 load (ear speaker). The MAX4756 has four 0.5 SPDT switches controlled by one logic control input and an enable pin (EN) to disable the switches. The MAX4754/MAX4755/MAX4756 are available in a space-saving 16-pin thin QFN and a tiny 16-bump 2mm x 2mm chip-scale package (UCSPTM).

Note 1: Signals on NO_, NC_, COM_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to maximum current rating.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

0.5, Quad SPDT Switches in UCSP/QFN
MAX4754/MAX4755/MAX4756
Detailed Description
The MAX4754/MAX4755/MAX4756 low on-resistance analog switches operate from a single +1.8V to +5.5V supply. The devices are fully specified for nominal 3V applications. The MAX4754 DPDT switch has two logic control inputs with each input controlling two SPDT switches. Each switch has a 0.5 on-resistance in the NO and NC terminals making it ideal for switching audio signals. The MAX4755 DPDT switch also has four 0.5 SPDT switches with the switch pairs 1 and 2 adding an 11.5 series resistor to the NC terminal. This feature allows the user to drive an 8 speaker as a 32 load, allowing it to be used as an ear speaker. Two logic control inputs are used to control the four switches. The MAX4756 has four 0.5 SPDT switches controlled by one logic control input (INA) and EN input to disable the switches.
Analog Signal Levels
Analog signal inputs over the full voltage range (0V to V+) are passed through the switch with minimal change in on-resistance (see the Typical Operating Characteristics). The switches are bidirectional so NO_, NC_, and COM_ can be either inputs or outputs.
Power-Supply Bypassing
Power-supply bypassing improves noise margin and prevents switching noise from propagating from the V+ supply to other components. A 0.1F capacitor connected from V+ to GND is adequate for most applications.
UCSP Applications Information
For the latest application details on UCSP construction, dimensions, tape carrier information, printed circuit board techniques, bump-pad layout, and recommended reflow temperature profile, as well as the latest information on reliability testing results, go to the Maxim website at www.maxim-ic.com/ucsp for the Application Note: UCSP--A Wafer-Level Chip-Scale Package.
Applications Information
Digital Control Inputs
The MAX4754/MAX4755/MAX4756 logic inputs accept up to +5.5V regardless of the supply voltage. For example, with a +3.3V supply IN_ can be driven low to GND and high to +5.5V, which allows mixed logic levels in a system. Driving the control logic inputs rail-torail also minimizes power consumption. For a +3V supply voltage, the logic thresholds are 0.5V (low) and 1.4V (high). For the MAX4756, drive EN low to enable the COM_. When EN is high, COM _ is high impedance.

MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT IC TERMINALS. OFF-ISOLATION IS MEASURED BETWEEN COM_ AND OFF NO_ OR NC_ TERMINAL ON EACH SWITCH. ON-LOSS IS MEASURED BETWEEN COM_ AND ON NO_ OR NC_ TERMINAL ON EACH SWITCH. CROSSTALK IS MEASURED FROM ONE CHANNEL TO THE OTHER CHANNEL. SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
