SPECIFICATIONS

The CD4051B, CD4052B, and CD4053B analog multiplexers are digitally-controlled analog switches having low

ON impedance and very low OFF leakage current. Control of analog signals up to 20 VP-P can be achieved by

digital signal amplitudes of 4.5 V to 20 V (if VDD – VSS = 3 V, a VDD – VEE of up to 13 V can be controlled; for

VDD – VEE level differences above 13 V, a VDD – VSS of at least 4.5 V is required). For example, if VDD = +4.5

V, VSS = 0 V, and VEE = –13.5 V, analog signals from –13.5 V to +4.5 V can be controlled by digital inputs of 0

V to 5 V. These multiplexer circuits dissipate extremely 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 channels are off.

The CD4051B device 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.
