CD4052 - Differential 4-channel Multiplexer/Demultiplexer IC
CD4052 - Differential 4-channel Multiplexer/Demultiplexer IC The CD4052 analog multiplexers/demultiplexers IC 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”. CD4052 is a differential 4-channel multiplexer having two binary control inputs, A and B, and an inhibit input. The two binary input signals select 1 or 4 pairs of channels to be turned on and connect the differential analog inputs to the differential outputs.
