General Description

The CD4051BC, CD4052BC, and CD4053BC analog mul-

tiplexers/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 sig-

nals from −5V to +5V can be controlled by digital inputs of

0−5V. The multiplexer circuits dissipate extremely low qui-

escent 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 ter-

minal all channels are “OFF”.

CD4051BC is a single 8-channel multiplexer having three

binary control inputs. A, B, and C, and an inhibit input. The

three binary signals select 1 of 8 channels to be turned

“ON” and connect the input to the output.

CD4052BC 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.

CD4053BC is a triple 2-channel multiplexer having three

separate digital control inputs, A, B, and C, and an inhibit

input. Each control input selects one of a pair of channels

which are connected in a single-pole double-throw configu-

ration.
