16-channel analogue
multiplexer/demultiplexer
HEF4067B
MSI
DESCRIPTION
The HEF4067B is a 16-channel analogue
multiplexer/demultiplexer with four address inputs (A
0
to
A
3
), an active LOW enable input (E), sixteen independent
inputs/outputs (Y
0
to Y
15
) and a common input/output (Z).
The device contains sixteen bidirectional analogue
switches, each with one side connected to an independent
input/output (Y
0
to Y
15
) and the other side connected to
the common input/output (Z).
With E LOW, one of the sixteen switches is selected (low
impedance ON-state) by A
0
to A
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 A
0
to A
3
.
The analogue inputs/outputs (Y
0
to Y
15
and Z) can swing
between V
DD
as a positive limit and V
SS
as a negative
limit. V
DD
to V
SS
may not exceed 15 V.
