HCC/HCF4051B, HCC/HCF4052B, and HCC/HCF4053B analog multiplexers/demultiplexers are digitally controlled analog switches having low ON impedance and very low OFF leakage PIN CONNECTIONS 4051B 4052B 4053B June 1989 1/17 HCC/HCF4051B/52B/53B current. 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 multiFUNCTIONAL DIAGRAMS AND TRUTH TABLES 4051B Input States Inhibit 0 0 0 0 0 0 0 0 1 C 0 0 0 0 1 1 1 1 X B 0 0 1 1 0 0 1 1 X A 0 1 0 1 0 1 0 1 X ”On” Channel (S) 0 1 2 3 4 5 6 7 None plexer having two binary control inputs, A and B, and an inhibit input.
