General Des cription
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.
