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”.

特性 Features

■ Wide range of digital and analog signal levels:

digital 3 – 15V, analog to 15Vp-p

■ Low “ON” resistance: 80Ω(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 signa

to 15 Vp-p(VDD −VEE =15V)

■ Matched switch characteristics:

∆RON =5Ω(typ.) 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
