Automotive Single Supply, SPDT Analog Switch
ISL76123
Features
The Intersil ISL76123 device is a small precision, bidirectional,
single-pole/double throw (SPDT) analog switch, designed to
operate from a single +2.7V to +12V supply. The device is
supplied in a 6 Ld SOT-23 package. Targeted applications
include automotive battery powered systems that can benefit
from the device’s low power consumption (5µW), low leakage

The device ensures the switching function is always
break-before-make to help eliminate transient signal problems.
Its small package size alleviates board space limitations. The
part has been qualified for use in automotive applications over
an operating temperature range of -40°C to +105°C.
