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 (E
1
and E
2
) and a latch enable input (LE). Each

74HC/HCT4353
multiplexer has two independent inputs/outputs (nY
0
and
nY
1
), a common input/output (nZ) and select inputs (S
1
to
S
3
).
Each multiplexer/demultiplexer contains two bidirectional
analog switches, each with one side connected to an
independent input/output (nY
0
and nY
1
) and the other side
connected to a common input/output (nZ).
With E
1
LOW and E
2
HIGH, one of the two switches is
selected (low impedance ON-state) by S
1
to S
3
.
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,
E
1
(active LOW) and E
2
(active HIGH), is inactive, all
analog switches are turned off.
V
CC
and GND are the supply voltage pins for the digital
control inputs (S
1
to S
3
, LE, E
1
and E
2
). The V
CC
to GND
ranges are 2.0 to 10.0 V for HC and 4.5 to 5.5 V for HCT.
The analog inputs/outputs (nY
0
and nY
1
, and nZ) can
swing between V
CC
as a positive limit and V
EE
as a
negative limit. V
CC
−
V
EE
may not exceed 10.0 V.
For operation as a digital multiplexer/demultiplexer, V
EE
is
connected to GND (typically ground).

Note to ratings
1. To avoid drawing V
CC
current out of terminals nZ, when switch current flows in terminals nY
n
, the voltage drop across
the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminals nZ, no V
CC
current will flow
out of terminals nY
n
. In this case there is no limit for the voltage drop across the switch, but the voltages at nY
n
and
nZ may not exceed V
CC
or V
EE
.
