General Description
These analog multiplexersdemultiplexers are digitally con-
trolled 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 VDDe5V VSSe0V and VEEeb5V
analog signals from b5V to a5V can be controlled by digi-
tal inputs of 0 – 5V The multiplexer circuits dissipate ex-
tremely low quiescent power over the full VDDbVSS and
VDDbVEE 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’’
CD4051BMCD4051BC 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
CD4052BMCD4052BC is a differential 4-channel multiplex-
er 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 ana-
log inputs to the differential outputs
CD4053BMCD4053BC 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
configuration
