74LVC1G3157
2-channel analog multiplexer/demultiplexer
Rev. 6 — 12 May 2016
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 VCC range from 1.65 V to 5.5 V.
2. Features and benefits
Wide supply voltage range from 1.65 V to 5.5 V
Very low ON resistance:
7.5 (typical) at VCC = 2.7 V
6.5 (typical) at VCC = 3.3 V
6 (typical) at VCC = 5 V
Switch current capability of 32 mA
Break-before-make switching
High noise immunity
CMOS low power consumption
TTL interface compatibility at 3.3 V
Latch-up performance meets requirements of JESD 78 Class I
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Control input accepts voltages up to 5.5 V
Multiple package options
Specified from 40 C to +85 C and from 40 C to +125 C
