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 and V are the supply voltage connections for the digital control inputs (S1 to S3,
DD SS
and E). The V to V range is 3 V to 15 V. The analog inputs/outputs (Y0 to Y7, and Z)
DD SS
can swing between V as a positive limit and V as a negative limit. V V may not
DD EE DD EE
exceed 15 V. Unused inputs must be connected to V , V , or another input. For
DD SS
operation as a digital multiplexer/demultiplexer, V is connected to V (typically
EE SS
ground). V and V are the supply voltage connections for the switches.
