2-channel analog multiplexer/demultiplexer
Rev. 01 — 7 February 2005
Product data sheet
1. General description
The 74LVC1G3157 is a high-performance, low-power, low-voltage, Si-gate CMOS device
that provides superior performance to most advanced CMOS compatible TTL families.
The 74LVC1G3157 provides one analog multiplexer/demultiplexer with one digital select
input (S), two independent inputs/outputs (B1 and B2) and a common input/output (A).

To avoid drawing V
CC
current out of terminal A when switch current flows in terminal Bn, the voltage drop
across the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminal A, no V
CC
current will flow out of terminal Bn. In this case, there is no limit for the voltage drop across the switch.
Applies to control signal levels.
