DESCRIPTION
The HC4051 is a single 8 channel multiplexer
demultiplexer having three binarycontrol inputs A,
B and C to select 1 of 8 to be turned on, and
connected to theoutput.
The HC4052has a pair of fourchannel multiplexer
demultiplexer havingtwocontrolinputsAand Bthat
selectone of four channels of the two sections.
The HC4053 is a triple two channel multiplexer
demultiplexer havingthree separate digitalcontrol
inputs A, B and C to select independently oneof a
pairof channles.
