NLASB3157
2:1 Multiplexer
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.

Maximum ratings are DC values beyond which the device may be damaged or have its useful life impaired. The data sheet specifications should
be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. ON
Semiconductor does not recommend operation outside data sheet specifications.
1. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.
