ORDER CODES :
These devices are analog multiplexer
demultiplexers in high speed silicon gate C2MOS
technology. These analog switches are bidirectional
and digitally controlled. A built-in level shifting is
included to allow them a control input range of up to
± 6V (peak) for an analog signal with digital control
signal of 0 to 6V.
VEE supply pin is provided for analog input signals.
They have two enable inputs to enable all the
switches when high (EN2) or low (EN1). For
operation as a digital multiplexer/demultiplexer, VEE
is connected to GND.
The HC4351 is a single 8 channel multiplexer
demultiplexer having three binary control inputs A,
B and C to select 1 of 8 to be turned on, and
connected to the output.
The HC4352 has a pair of four channel multiplexer
demultiplexer having two control inputs A and B that
select one of four channel of the two sections.
The HC4353 is a triple two channel multiplexer
demultiplexer having three separate digital control
inputs A, B and C to select independently one of a
pair of channles.
