DESCRIPTION
Input for channel 0
Not Internally Connected; it is recommended this pin be tied to ground to
minimize crosstalk.
Input for channel 1
Ground pin
Input for channel 2
Input for channel 3
Negative power supply
Output
Output disable (active high); there are internal pull-down resistors, so the
device will be active with no connection; "HI" puts the output in high
impedance state.
Channel selection pin MSB (binary logic code)
Channel selection pin LSB (binary logic code)
