DESCRIPTION
These devices are analog multiplexer demultiplexers in high speed silicon gate C 2MOS 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. PIN CONNECTION (top view) HC4351 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.
