DESCRIPTION
The HCF4051B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
The HCF4051B analog multiplexer/demultiplexer
is a digitally controlled analog switch having low
ON impedance and very low OFF leaka ge current.
This multiplexer circuit dissipate extremely low
quiescent power over the full V
V
supply voltage range, independent of the
EE
DD-VSS
logic state of the c ontrol signals.
When a logic "1" is present at the i nhibit input
terminal all channel are off. This device is a single
8-channel multiplexer having three binary c ontrol
inputs, A, B, and C, and an inhibit input. The three
binary signals select 1 of 8 channels to be turned
on, and connect one of the 8 inp uts to the output.
