HEF4053
Triple 2-channel Analog
Multiplexer/Demultiplexer
(1) Description
The HEF4053 is a triple 2-channel analog multiplexer/demultiplexer with a common enable
input (E). Each multiplexer/demultiplexer has two independent inputs/outputs (Y0 and Y~), a
common input/output (Z), and select inputs (Sn). Each also contains two-bidirectional analog
switches, each with one side connected to an independent input/output (Y
0
and Y
1
) and the
other side connected to a common input/output(Z).
With (E) LOW, one of the two switches is selected (low impedance ON-state) by Sn. With E
HIGH, all switches are in the high impedance OFF-state, independent of S
