1.7 Dual 4-channel Analog Multiplexer/Demultiplexer HEF4052
(1) Description
The HEF4052 is a dual 4-channel analog multiplexer/demultiplexer with common channel select
logic. Each multiplexer/demultiplexer has four independent inputs/outputs (Y
input/output (Z). The common channel select logic includes two address inputs (A
active LOW enable input (E).
Both multiplexers/demultiplexers contain four bidirectional analog switches, each with one side
connected to an independent input/output (Y
input/output(Z).
With E LOW, one of the four switches is selected (low impedance ON-state) by A
HIGH, all switches are in the high impedance OFF-state, independent of A
are the supply voltage connections for the digital control inputs (A
is 3 to 15 V. The analog inputs/outputs (Y
