description/ordering information (continued)
The CD4051B is a single eight-channel multiplexer that has three binary control inputs (A, B, and C) and an
inhibit input. The three binary signals select one of eight channels to be turned on and connect one of the eight
inputs to the output.
The CD4052B is a differential four-channel multiplexer that has two binary control inputs (A and B) and an inhibit
input. The two binary input signals select one of four pairs of channels to be turned on and connect the analog
inputs to the outputs.
The CD4053B is a triple two-channel multiplexer with 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.
When these devices are used as demultiplexers, the CHANNEL IN/OUT terminals are the outputs, and the
common (COM OUT/IN) terminals are the inputs.
