Demultiplexer (IC 901)
The HCF4052B is a monolithic integrated circuit, fabricated in
Metal Oxide Semiconductor technology, available in DIP and
SOP packages.
The HCF4052B analog multiplexer/demultiplexer is a digitally
controlled analog switch, having low ON impedance, and very
low OFF leakage current. This multiplexer circuit dissipates
extremely low quiescent power over the full supply voltage
range, independent of the logic states of the control signals.
When a logic “1” is present at the inhibit input, all channels are
off. This device is a differential 4-channel multiplexer, having 2
binary control inputs, A and B, and an inhibit input. The two
binary input signals select 1 of 4 pairs of channels to be turned
on and connect the analog inputs to the outputs.
