current. These multiplexer circuits dissipate ex-
tremely low quiescent power over the full V
and V
of the logic state of the control signals. When a-logic
”1” is present at the inhibit input terminal all channel
are off. The HCC/HCF4051B 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
HCC/HCF4052B is a differential 4-channel multi-

HCC/HCF4053B is a triple 2-channel multiplexer
having three separate digital control inputs, A, B,
and C, and an inhibit input. Each control input se-
lects one of a pair of channels which are connected
in a singlepole double-throw configuration.
