HEF4051B
8-channel analog multiplexer/demultiplexer
Rev. 12 — 25 March 2016
Product data sheet
1. General description
The HEF4051B is an 8-channel analog multiplexer/demultiplexer with three address
inputs (S1 to S3), an active LOW enable input (E), eight independent inputs/outputs
(Y0 to Y7) and a common input/output (Z). The device contains eight bidirectional analog
switches, each with one side connected to an independent input/output (Y0 to Y7) and the
other side connected to a common input/output (Z). With E LOW, one of the eight
switches is selected (low-impedance ON-state) by S1 to S3. With E HIGH, all switches
are in the high-impedance OFF-state, independent of S1 to S3. If break before make is
needed, then it is necessary to use the enable input.
V
DD
and V
SS
are the supply voltage connections for the digital control inputs (S1 to S3,
and E). The V
DD
to V
SS
range is 3 V to 15 V. The analog inputs/outputs (Y0 to Y7, and Z)
can swing between V
DD
as a positive limit and V
EE
as a negative limit. V
DD
V
EE
may not
exceed 15 V. Unused inputs must be connected to V
DD
, V
SS
, or another input. For
operation as a digital multiplexer/demultiplexer, V
EE
is connected to V
SS
(typically
ground). V
EE
and V
SS
are the supply voltage connections for the switches.
