11.22.1. General Description
The HCC4051B, 4052B and 4053B (extended temperature range) and HCF4051B, 4052 B and 4053B
(intermediate temperature range) are monolithic integrated circuits, available in 16-lead dual in-line plastic
or ceramic package and plastic micropackage. HCC/HCF4051B, HCC/HCF4052B, and HCC/HCF4053B
analog multiplexers/demultiplexers are digitally controlled analog switches having low ON impedance and
very low OFF leakage current. These multiplexer circuits dissipate extremely low quiescent power over the

supply-voltage ranges, independent of the logic state of the control signals.
When a-logic ”1” is present at the inhibit input terminal all channel are off.
The HCC/HCF4053B is a triple 2-channel multiplexer having three separate digital control inputs, A, B, and
C, and an inhibit input. Each control input selects one of a pair of channels which are connected in a
singlepole double-throw configuration.
