DESCRIPTION
The 74HC4052 and 74HCT4052 are high-speed Si-gate
CMOS devices and are pin compatible with the
HEF4052B. They are specified in compliance with JEDEC
standard no. 7A.
The 74HC4052 and 74HCT4052 are dual 4-channel
analog multiplexers or demultiplexers with common select
logic. Each multiplexer has four independent
inputs/outputs (pins nY0 to nY3) and a common
input/output (pin nZ). The common channel select logics
include two digital select inputs (pins S0 and S1) and an
active LOW enable input (pin
E). When pin E = LOW, one
of
the four switches is selected (low-impedance ON-state)
with pins S0 and S1. When pin
E = HIGH, all switches are
in
the high-impedance OFF-state, independent of pins S0
and S1.
V
CC
and GND are the supply voltage pins for the digital
control inputs (pins S0, S1, and
E). The V
CC
to GND
ranges are 2.0 V
to 10.0 V for 74HC4052 and
4.5 V to 5.5 V for 74HCT4052. The analog inputs/outputs
(pins nY0 to nY3 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).
