General Description
These analog multiplexers/demultiplexers 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’’.
CD4051BM/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.
CD4052BM/CD4052BC 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.
CD4053BM/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
configuration.
Features
YWide range of digital and analog signal levels: digital
3–15V, analog to 15Vp-p
YLow ‘‘ON’’ resistance: 80X(typ.) over entire 15Vp-p sig-
nal-input range for VDDbVEEe15V
YHigh ‘‘OFF’’ resistance: channel leakage of g10 pA
