Data Sheet July 2004 FN6028.2
Low-Voltage, Single Supply, SPST, High Performance Analog Switches
The Intersil ISL4311X are precision, high performance analog switches that are fully specified for 3.3V, 5V, and 12V operation, and feature improved leakage, Icc, and switching time specifications. Designed to operate from a single +2.4V to +12V supply, the low supply current (1A Max over the temperature and voltage ranges) and low leakage currents (1nA) make these switches ideal for battery powered applications. Low RON and fast switching speeds over a wide operating supply range increase these devices usefulness in industrial equipment, portable instruments, and as input signal multiplexers for new generation, low supply voltage data converters. Some of the smallest packages are available alleviating board space limitations, and making Intersil's newest line of low-voltage switches an ideal solution. The ISL4311X are single-pole/single-throw (SPST) switches, with the ISL43110 being normally open (NO), and the ISL43111 being normally closed (NC). Table 1 summarizes the performance of this family. For similar performance 5V supply versions, see the ISL43112/13 data sheet.

Detailed Description
The ISL43110 and ISL43111 analog switches offer precise switching capability from a single 2.4V to 12V supply with low on-resistance and high speed operation. The devices are especially well suited to portable battery powered equipment thanks to the low operating supply voltage (2.4V), low power consumption (5W), low leakage currents (1nA max), and the tiny SOT-23 packaging. High frequency applications also benefit from the wide bandwidth, and the very high off isolation. unaffected by this approach, but the switch resistance may increase, especially at low supply voltages.

Supply Sequencing And Overvoltage Protection
As with any CMOS device, proper power supply sequencing is required to protect the device from excessive input currents which might permanently damage the IC. All I/O pins contain ESD protection diodes from the pin to V+ and to GND (see Figure 6). To prevent forward biasing these diodes, V+ must be applied before any input signals, and input signal voltages must remain between V+ and GND. If these conditions cannot be guaranteed, then one of the following two protection methods should be employed. Logic inputs can easily be protected by adding a 1k resistor in series with the input (see Figure 6). The resistor limits the input current below the threshold that produces permanent damage, and the sub-microamp input current produces an insignificant voltage drop during normal operation. Adding a series resistor to the switch input defeats the purpose of using a low RON switch, so two small signal diodes can be added in series with the supply pins to provide overvoltage protection for all pins (see Figure 6). These additional diodes limit the analog signal from 1V below V+ to 1V above GND. The low leakage current performance is

Power-Supply Considerations
The ISL4311X construction is typical of most CMOS analog switches, except that there are only two supply pins: V+ and GND. Unlike switches with a 13V maximum supply voltage, the ISL4311X 15V maximum supply voltage provides plenty of room for the 10% tolerance of 12V supplies, as well as room for overshoot and noise spikes. The minimum recommended supply voltage is 2.4V. It is important to note that the input signal range, switching times, and on-resistance degrade at lower supply voltages. Refer

ISL43110, ISL43111
to the electrical specification tables and Typical Performance Curves for details. V+ and GND power the internal CMOS switches and set their analog voltage limits. These supplies also power the internal logic and level shifters. The level shifters convert the input logic levels to switched V+ and GND signals to drive the analog switch gate terminals. This family of switches cannot be operated with bipolar supplies, because the input switching point becomes negative in this configuration. For a 5V single SPST switch, see the ISL43112/13 data sheet. response is very consistent over a wide V+ range, and for varying analog signal levels. An OFF switch acts like a capacitor and passes higher frequencies with less attenuation, resulting in signal feedthrough from a switch's input to its output. Off Isolation is the resistance to this feedthrough. Figure 16 details the high Off Isolation provided by this family. At 10MHz, off isolation is about 50dB in 50 systems, decreasing approximately 20dB per decade as frequency increases. Higher load impedances decrease Off Isolation due to the voltage divider action of the switch OFF impedance and the load impedance.
Logic-Level Thresholds
This switch family is TTL compatible (0.8V and 2.4V) over a supply range of 3V to 11V, and the full temperature range (see Figure 10). At 12V the low temperature VIH level is about 2.5V. This is still below the TTL guaranteed high output minimum level of 2.8V, but noise margin is reduced. For best results with a 12V supply, use a logic family the provides a VOH greater than 3V. The digital input stages draw supply current whenever the digital input voltage is not at one of the supply rails. Driving the digital input signals from GND to V+ with a fast transition time minimizes power dissipation.
Leakage Considerations
Reverse ESD protection diodes are internally connected between each analog-signal pin and both V+ and GND. One of these diodes conducts if any analog signal exceeds V+ or GND. Virtually all the analog leakage current comes from the ESD diodes to V+ or GND. Although the ESD diodes on a given signal pin are identical and therefore fairly well balanced, they are reverse biased differently. Each is biased by either V+ or GND and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the V+ and GND pins constitutes the analogsignal-path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage currents of the same or opposite polarity. There is no connection between the analog-signal paths and V+ or GND.
High-Frequency Performance
In 50 systems, signal response is reasonably flat to 20MHz, with a -3dB bandwidth exceeding 200MHz (see Figure 15). Figure 15 also illustrates that the frequency

NOTES: 1. Symbols are defined in the "MO Series Symbol List" in Section 2.2 of Publication Number 95. 2. Dimensioning and tolerancing per ANSI Y14.5M-1982. 3. Dimension "D" does not include mold flash, protrusions or gate burrs. Mold flash, protrusion and gate burrs shall not exceed 0.15mm (0.006 inch) per side. 4. Dimension "E" does not include interlead flash or protrusions. Interlead flash and protrusions shall not exceed 0.25mm (0.010 inch) per side. 5. The chamfer on the body is optional. If it is not present, a visual index feature must be located within the crosshatched area. 6. "L" is the length of terminal for soldering to a substrate. 7. "N" is the number of terminal positions. 8. Terminal numbers are shown for reference only. 9. The lead width "B", as measured 0.36mm (0.014 inch) or greater above the seating plane, shall not exceed a maximum value of 0.61mm (0.024 inch). 10. Controlling dimension: MILLIMETER. Converted inch dimensions are not necessarily exact.
