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: 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 signa

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 μW (typ.) at VDD ?VSS =VDD ?VEE =10V

■ Binary address decoding on chip
