2-channel analog multiplexer/demultiplexer
Rev. 5 — 6 December 2012
Product data sheet
1. General description
The 74LVC1G3157 provides one analog multiplexer/demultiplexer with one digital select
input (S), two independent inputs/outputs (Y0, Y1) and a common input/output (Z).
Schmitt trigger action at the select input 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

CC
= 3.3 V
6
(typical) at V
CC
= 5 V
Switch current capability of 32 mA
Break-before-make switching
High noise immunity
CMOS low power consumption

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.
