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 Vop=5V, Vss=0V and VEE=-5V, analog signals from-5V to +5V can be controlled by digital inputs of0-5V. The multiplexer circuits dissipate extremely low quiescent power over the full Vop-Vss and Vop-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".
CD4051BC is a single 8-channel multiplexer having three binary control inputs.A,B, and C, and an inhibit input. Thethree binary signals select 1 of 8 channels to be turned "ON"and connect the input to the output. CD4052BC 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 diferential outputs.
CD4053BC 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 which are connected in a single-pole double-throw configuration.
Features
■Wide range of digital and analog signal levels: digital 3-15V, analog to 15Vp-p
■Low "ON"resistance:80Q(typ.) over entire 15Vp-p signal-input range for Vo0-VEE=15V
