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.
Each multiplexer has four independent inputs/outputs
(nY
0
to nY
3
) and a common input/output (nZ).
The common channel select logics include two select
inputs (S
0
and S
1
), an active LOW enable input (E
1
), an
active HIGH enable input (E
2
) and a latch enable input
(LE).
With E
1
LOW and E
2
HIGH, one of the four switches is
selected (low impedance ON-state) by S
0
and S
1
. 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
0
, S
1
, 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
to nY
3
, 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).
