CD4070 Integrated Circuits, Brand Name : Texas Instruments

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 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. Features:- Wide range of digital and analog signal levels: digital 3 15V, analog to 15Vp-p Low ON resistance: 80 (typ.) over entire 15Vp-p signal-input range for VDD VEE = 15V High OFF resistance: channel leakage of 10 pA (typ.) at VDD VEE = 10V Logic level conversion for digital addressing signals of 3 15V (VDD VSS = 3 15V) to switch analog signals to 15 Vp-p (VDD VEE = 15V) Matched switch characteristics: RON = 5 (typ.) for VDD VEE = 15V Very low quiescent power dissipation under all digital-control input and supply conditions: 1 W (typ.) at VDD VSS = VDD VEE = 10V Binary address decoding on chip
