CD4053 - Triple 2-channel Multiplexer/Demultiplexer IC
The CD4053 IC 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”.
The CD4x Series CD4053 Integrated Circuits is a triple 2-channel multiplexer having three separate digital control inputs, A, B, and C, and an inhibit input. Each control input selects one of a pair of channels that are connected in a single-pole double-throw configuration.
