2 / 17 page FUNCTIONAL DIAGRAMS AND TRUTH TABLES current. These multiplexer circuits dissipate ex- tremely low quiescent power over the full VDD –VSS and VDD –VEE 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/HCF4051B is a single 8-channel multiplexer having three binary control 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 inputs to the output. The HCC/HCF4052B is a differential 4-channel multi- plexer having two 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. 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 se- lects one of a pair of channels which are connected in a singlepole double-throw configuration.
