GENERAL DESCRIPTION

The 74HC/HCT4353 are high-speed Si-gate CMOS
devices. They are specified in compliance with JEDEC
standard no. 7A.

The 74HC/HCT4353 are triple 2-channel analog
multiplexers/demultiplexers with two common enable
inputs (

E1and E2) and a latch enable input (LE). Each

multiplexer has two independent inputs/outputs (nY0and
nY1), a common input/output (nZ) and select inputs (S1to
S3).

Each multiplexer/demultiplexer contains two bidirectional
analog switches, each with one side connected to an
independent input/output (nY0and nY1) and the other side
connected to a common input/output (nZ).

With E1LOW and E2HIGH, one of the two switches is
selected (low impedance ON-state) by S1to S3.
The data at the select inputs may be latched by using the
active LOW latch enable input (LE). When LE is HIGH, the
latch is transparent. When either of the two enable inputs,
E1(active LOW) and E2(active HIGH), is inactive, all
analog switches are turned off.

VCCand GND are the supply voltage pins for the digital
control inputs (S1to S3, LE, E1and E2). The VCCto GND
ranges are 2.0 to 10.0 V for HC and 4.5 to 5.5 V for HCT.
The analog inputs/outputs (nY0and nY1, and nZ) can
swing between VCCas a positive limit and VEEas a
negative limit. VCC− VEEmay not exceed 10.0 V.

For operation as a digital multiplexer/demultiplexer, VEEis
connected to GND (typically ground).

RATINGS

Limiting values in accordance with the Absolute Maximum System (IEC 134)
Voltages are referenced to VEE= GND (ground = 0 V)

Note to ratings

1. To avoid drawing V

CC

current out of terminals nZ, when switch current flows in terminals nYn, the voltage drop across
the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminals nZ, no VCCcurrent will flow
out of terminals nYn. In this case there is no limit for the voltage drop across the switch, but the voltages at nYnand
nZ may not exceed VCCor VEE.
