Features
• Drop-in Replacement for MAX394
The Intersil ISL8394 device is a precision, quad SPDT analog
switches designed to operate from a single +2V to +12V
supply or from a ±2V to ±6V supply. Targeted applications
include battery powered equipment that benefit from the
devices’ low power consumption (5µW), low leakage currents

The ISL8394 is a quad single-pole/double-throw (SPDT)
device and can be used as a quad SPDT, a quad 2:1
multiplexer, a single 4:1 multiplexer, or a dual 2-channel
differential multiplexer.
