The CD4051BC, CD4052BC, and CD4053BC analog multiplexers/demultiplexers are digitally controlled analog switches having low "ON" impedance and very low "OFF" leakage currents. Control of analog signals up to 15Vp-p can be achieved by digital signal amplitudes of 3-15V. For example, if VDD = 5V, VSS = 0V and VEE = -5V, analog signals from -5V to +5V can be controlled by digital inputs of 0-5V. The 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 logical "1" is present at the inhibit input terminal all channels are "OFF".
