Multiplexers/Demultiplexers*

Description

CD4051BMS, CD4052BMS and CD4053BMS analog multi-

plexers/demultiplexers

are

digitally

controlled

analog

switches having low ON impedance and very low OFF leak-

age current. Control of analog signals up to 20V peak-to-

peak can be achieved by digital signal amplitudes of 4.5V to

20V (if VDD-VSS = 3V, a VDD-VEE of up to 13V can be con-

trolled; for VDD-VEE level differences above 13V, a VDD-

VSS of at least 4.5V is required). For example, if VDD =

+4.5V, VSS = 0, and VEE = -13.5V, analog signals from -

13.5V to +4.5V can be controlled by digital inputs of 0 to 5V.

These 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 logic “1” is present at the inhibit input terminal all

channels are off.

The CD4051BMS 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 one of the 8 inputs to the output.

The CD4052BMS is a differential 4 channel multiplexer hav-

ing two binary control inputs, A and B, and an inhibit input.

The two binary input signals select 1 of 4 pairs of channels

to be turned on and connect the analog inputs to the out-

puts.

The CD4053BMS 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 chan-

nels which are connected in a single pole double-throw con-

figuration.

The CD4051BMS, CD4052BMS and CD4053BMS are supplied

in these 16 lead outline packages:

IN/OUT” terminals are the outputs and the “COMMON OUT/IN” ter-

minals are the inputs.
