CMOS Analog Multiplexers/Demultiplexers
with Logic Level Conversion
The CD4051B, CD4052B, and CD4053B analog multiplexers
are digitally-controlled analog switches having low ON
impedance and very low OFF leakage current. Control of
analog signals up to 20VP-P 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 controlled; for VDD -VDD
level differences above 13V, a VDD -VDD of at least 4.5V is
required). For example, if VDD = +4.5V, VDD = 0V, and
VDD = -13.5V, analog signals from -13.5V to +4.5V can be
controlled by digital inputs of 0V to 5V. These multiplexer
circuits dissipate extremely low quiescent power over the
full VDD -VDD and VDD -VDD supply-voltage ranges,
independent of the logic state of the control signals. When
a logic â1â is present at the inhibit input terminal, all
channels are off.
The CD4051B 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 CD4052B 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 of 4 pairs of channels to be
turned on and connect the analog inputs to the outputs.
The CD4053B 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
conï¬guration.
When these devices are used as demultiplexers, the
âCHANNEL IN/OUTâ terminals are the outputs and the
âCOMMON OUT/INâ terminals are the inputs.
