CD4052BCN

FAIRCHILD SEMICONDUCTOR  CD4052BCN  芯片, 4000系列 CMOS逻辑器件

General Description

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 15V

p-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”.

Features

■Wide range of digital and analog signal levels: digital 3 – 15V, analog to 15Vp-p

■Low “ON” resistance: 80Ωtyp. 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 signa

to 15 Vp-pVDD −VEE =15V

■Matched switch characteristics: ∆RON =5Ωtyp. for VDD −VEE =15V

■Very low quiescent power dissipation under all digital-control input and supply conditions: 1 µW typ. at VDD −VSS =VDD −VEE =10V

■Binary address decoding on chip
