Notes:
1. Supplied as a design limit but not guaranteed or tested.
2. Not more than one output may be shorted at a time for maximum duration of one second.
3. Measure only for initial qualification, and after process or design changes that could affect input/output capacitance.
4. All inputs with internal pull-ups or pull-downs should be left open circuit, all other inputs tied low or high. TEST input pin asserted.
5. Includes current through input pull-ups. Instantaneous surge currents on the order of 1 ampere can occur during output switching. Voltage supply should be
adequately sized and decoupled to handle a large current surge.
6. Double buffer output pins (i.e., DS, R/WR, M/IO, OP/IN).
