DESCRIPTION
The 74HC4052/74HCT4052 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 74HC4052/74HCT4052 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 to 10.0 V for 74HC4052 and 4.5 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).
