Ground pin
Input for channel 0
Device enable (active low); there are internal pull-down resistors, so the device will be active with
no connection; "HI" puts device into power-down mode.
Input for channel 1
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.
