The CD4051BC, CD4052BC, and CD4053BC analog multiplexers/demultiplexers are digitally controlled analogswitches having low “ON” impedance and very low “OFF”leakage currents. Control of analog signals up to 15Vp-pcan be achieved by digital signal amplitudes of 3 - 15V. Forexample, if VDD = 5V, VSS = 0V and VEE = -5V, analog signalsfrom -5V to +5V can be controlled by digital inputs of 0- 5V. The multiplexer circuits dissipate extremely low quiescentpower over the full VDD-VSS and VDD-VEE supplyvoltage ranges, independent of the logic state of the controlsignals. When a logical “1” is present at the inhibit input terminalall channels are “OFF”.CD4051BC 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 the input to the output.CD4052BC is a differential 4-channel multiplexer havingtwo binary control inputs, A and B, and an inhibit input. Thetwo binary input signals select 1 or 4 pairs of channels tobe turned on and connect the differential analog inputs tothe differential outputs.
