BACK
NC
Do not connect
Can go to GND connection (Note: GND must be
connected. The back is not a system ground connection).
Backside
Note: Only connect to one of the output pads, Pad 2
or
Pad 3, not both. Either push-pull (Pad 2) or open-drain (Pad 3) can be used
but they can not both be used on the same die.
