A built-in level shifting is included to allow an input range 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. It has 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 M74HC4351 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.
