ON
Switch
The NLASB3157 is an advanced CMOS analog switch fabricated
with silicon gate CMOS technology. It achieves very low
propagation delay and RDS
ON
resistances while maintaining CMOS
low power dissipation. Analog and digital voltages that may vary
across the full power−supply range (from V
CC
to GND). This device
is a drop in replacement for the NC7SB3157.
The select pin has overvoltage protection that allows voltages
above V
CC,
up to 7.0 V to be present on the pin without damage or
disruption of operation of the part, regardless of the operating
voltage.
