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 (5µW), 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.

FIGURE 6. OVERVOLTAGE PROTECTION  
Logic inputs can easily be protected by adding a 1kΩ  
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.  
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.  
Adding a series resistor to the switch input defeats the  
purpose of using a low R  
switch, so two small signal  
ON  
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  
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
