GENERAL DESCRIPTION
The 74HC/HCT4067 are high-speed Si-gate CMOS
devices and are pin compatible with the "4067" of the
"4000B" series. They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT4067 are 16-channel analog
multiplexers/demultiplexers with four address inputs (S
0
to
S
3
) , an active LOW enable input (E), sixteen independent
inputs/outputs (Y
0
to Y
15
) and a common input/output (Z).
The "4067" contains sixteen bidirectional analog switches,
each with one side connected to an independent
input/output (Y
0
to Y
15
) and the other side connected to a
common input/output (Z).
With E LOW, one of the sixteen switches is selected (low
impedance ON-state) by S
0
to S
3
. All unselected switches
are in the high impedance OFF-state. With E HIGH, all
switches are in the high impedance OFF-state,
independent of S
0
to S
3
.
The analog inputs/outputs (Y
0
to Y
15
, and Z) can swing
between V
CC
as a positive limit and GND as a negative
limit. V
CC
to GND may not exceed 10 V.
