74LVC2G3157
Dual 10
single-pole double-throw analog switch
Rev. 2 — 15 December 2016
Product data sheet
1. General description
The 74LVC2G3157 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 V
CC
range from 1.65 V to 5.5 V.
2. Features and benefits

The minimum input voltage rating may be exceeded if the input current rating is observed.
The minimum and maximum switch voltage ratings may be exceeded if the switch clamping current rating is observed.
For TSSOP10 package: above 55C the value of P

To avoid sinking GND current from terminal Z when switch current flows in terminal Yn, the voltage drop across the bidirectional switch
must not exceed 0.4 V. If the switch current flows into terminal Z, no GND current will flow from terminal Yn. In this case, there is no limit
for the voltage drop across the switch.
Applies to control signal levels.
