Triple 2-Channel Analog Multiplexer/Demultiplexer General Description CD4053BC is a triple 2-channel multiplexer having three separate digital control inputs, A, B, and C, and an inhibit The CD4051BC, CD4052BC, and CD4053BC analog mul- input. Each control input selects one of a pair of channels tiplexers/demultiplexers are digitally controlled analog which are connected in a single-pole double-throw configu- switches having low “ON” impedance and very low “OFF” ration. leakage currents. Control of analog signals up to 15Vp-p can be achieved by digital signal amplitudes of 3 ? 15V.
