General Description
The CD4051BC, CD4052BC, and CD4053BC analog multiplexers/demultiplexers are digitally controlled analog switches having low âONâ impedance and very low âOFFâ leakage currents. Control of analog signals up to 15V p-p can be achieved by digital signal amplitudes of 3â15V. For example, if VDD =5V, VSS =0V and VEE = â5V, analog signals from â5V to +5V can be controlled by digital inputs of 0â5V. The multiplexer circuits dissipate extremely low quiescent power over the full VDDâVSS and VDDâVEE supply voltage ranges, independent of the logic state of the control signals. When a logical â1â is present at the inhibit input terminal all channels are âOFFâ.
Features
â Wide range of digital and analog signal levels:
digital 3 â 15V, analog to 15Vp-p
â Low âONâ resistance: 80â¦(typ.) over entire 15Vp-p
signal-input range for VDD âVEE =15V
â High âOFFâ resistance:
channel leakage of ±10 pA (typ.) at VDD âVEE =10V
â Logic level conversion for digital addressing signals of
3 â 15V (VDD âVSS =3 â 15V) to switch analog signa
to 15 Vp-p(VDD âVEE =15V)
â Matched switch characteristics:
âRON =5â¦(typ.) for VDD âVEE =15V
â Very low quiescent power dissipation under all
digital-control input and supply conditions:
1 µW (typ.) at VDD âVSS =VDD âVEE =10V
â Binary address decoding on chip
