Data Sheet
Low-Voltage, Single Supply, Dual SPST
Analog Switches
The Intersil ISL8323–ISL8325 devices are precision, dual
analog switches designed to operate from a single +2.7V to
+12V supply. Targeted applications include battery powered
equipment that benefit from the devices’ low power
consumption (5µW), low leakage currents (100pA max), and
fast switching speeds. Excellent RON matching and flatness
maintain signal fidelity over the whole input range.
The ISL8323/ISL8324/ISL8325 are dual single-pole/single-
throw (SPST) devices. The ISL8323 has two normally open
(NO) switches; the ISL8324 has two normally closed (NC)
switches; the ISL8325 has one NO and one NC switch and
can be used as an SPDT. Table 1 summarizes the
performance of this family. For higher performance, pin
compatible versions, or SOT-23 packaged devices, see the
ISL5120-23 data sheet.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
2. Signals on NC, NO, COM, or IN exceeding V+ or GND are clamped by internal diodes. Limit forward diode current to maximum current ratings.
3. θJA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
