DESCRIPTION

The HCF4051B is a monolithic interated 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 leakage current.This multiplexer circuit dissipate extremely low quiescent power over the full V_DD-V_SS and V_DD-V_EE supply voltage range,independent of the logic state of the control signats.

When a logic “1" is present at the inhibit input terminal all channel are off.This device is a single 8-channel multiplexer having three binary control inputs,A,B,andC,and an inhibit input.The three binary signats select 1 of 8 channels to be turned on,and connect one of the 8 inputs to the output.
