The CD4051B, CD4052B, and CD4053B analog multiplexersare digitally-controlled analog switches having low ONimpedance and very low OFF leakage current. Control ofanalog signals up to 20VP-Pcan be achieved by digitalsignal amplitudes of 4.5V to 20V (if VDD-VSS= 3V, aVDD-VEEof up to 13V can be controlled; for VDD-VDDlevel differences above 13V, a VDD-VDDof at least 4.5V isrequired). For example, if VDD= +4.5V, VDD= 0V, andVDD= -13.5V, analog signals from -13.5V to +4.5V can becontrolled by digital inputs of 0V to 5V. These multiplexercircuits dissipate extremely low quiescent power over thefull VDD-VDDand VDD-VDDsupply-voltage ranges,independent of the logic state of the control signals. Whena logic “1” is present at the inhibit input terminal, allchannels are off.The CD4051B is a single 8-Channel multiplexer having threebinary control inputs, A, B, and C, and an inhibit input. Thethree binary signals select 1 of 8 channels to be turned on,and connect one of the 8 inputs to the output.The CD4052B is a differential 4-Channel multiplexer havingtwo binary control inputs, A and B, and an inhibit input. Thetwo binary input signals select 1 of 4 pairs of channels to beturned on and connect the analog inputs to the outputs.The CD4053B is a triple 2-Channel multiplexer having threeseparate digital control inputs, A, B, and C, and an inhibitinput. Each control input selects one of a pair of channelswhich are connected in a single-pole, double-throwcon？guration.When these devices are used as demultiplexers, the“CHANNEL IN/OUT” terminals are the outputs and the“COMMON OUT/IN” terminals are the inputs.
