Dual 4-channel analogue multiplexer/demultiplexer
DESCRIPTION
The HEF4052B is a dual 4-channel
analogue multiplexer/demultiplexer
with common channel select logic.
Each multiplexer/demultiplexer has
four independent inputs/outputs
(Y
0
to Y
3
) and a common input/output
(Z). The common channel select logic
includes two address inputs (A
0
and
A
1
) and an active LOW enable input
(E).
Both multiplexers/demultiplexers
contain four bidirectional analogue
switches, each with one side
connected to an independent
input/output (Y
0
to Y
3
) and the other
side connected to a common
input/output (Z).
With E LOW, one of the four switches
is selected (low impedance ON-state)
by A
0
and A
1
. With E HIGH, all
switches are in the high impedance
OFF-state, independent of A
0
and A
1
.

are the supply voltage
connections for the digital control
inputs (A
0
, A
1
and E). The V
DD
to
V
SS
range is 3 to 15 V. The analogue
inputs/outputs (Y
0
to Y
3
, and Z) can
swing between V
DD
as a positive limit
and V
EE
as a negative limit.
