Description

CD 4052

The CD4052 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”. A, B, and C, and an inhibit input. The three binary signals select 1 of 8 channels to be turned “ON” and connect the input to the output. CD4052 is a differential 4-channel multiplexer having two binary control inputs, A and B, and an inhibit input.
