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 dissipate extremely low quiescent power over the full VDD – VSS and VDD – VEE supply voltage range, independent of the logic state of the control signals.When a logic “1” is present at the inhibit input terminal all channel are off. This device is a differential 4-channel multiplexer having two binary control inputs, A and B and an inhibit input. The two binary input signals selects 1 of 4 pairs of channels to be turned on and connect the analog inputs to the outputs.
- LOW “ON” RESISTANCE : 125? (Typ.) OVER 15V p.p SIGNAL-INPUT RANGE FOR VDD – VEE = 15V
