GENERAL DESCRIPTION

The 74HC/HCT4352 are high-speed Si-gate CMOS
devices. They are specified in compliance with JEDEC
standard no. 7A.

The 74HC/HCT4352 are dual 4-channel analog
multiplexers/demultiplexers with common select logic.

74HC/HCT4352

Each multiplexer has four independent inputs/outputs

to nY3) and a common input/output (nZ).

(nY

0

The common channel select logics include two select
inputs (S0 and S1), an active LOW enable input (E1), an
active HIGH enable input (E2) and a latch enable input
(LE).

With E1 LOW and E2 HIGH, one of the four switches is
selected (low impedance ON-state) by S0 and S1. 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
(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 (S0, S1, LE, E1 and E2). The VCC 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 (nY0 to nY3, and nZ) can swing
between VCC as a positive limit and VEE as a negative limit.
VCC− VEE may not exceed 10.0 V.

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

Note

1. To avoid drawing V

current out of terminals nZ, when switch current flows in terminals nYn, the voltage drop across

CC

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 nYn and
nZ may not exceed VCC or VEE.
