1. General description

The 74LVC2G3157-Q100 is a dual low-ohmic single-pole double-throw analog switch suitable for

use as an analog or digital 2:1 multiplexer/demultiplexer. Each switch has a digital select input (nS),

two independent inputs/outputs (nY0 and nY1) and a common input/output (nZ).

Schmitt trigger action at the select inputs makes the circuit tolerant of slower input rise and fall

times across the entire VCC range from 1.65 V to 5.5 V.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
