Notes:

1. The voltage on any input or I/O pin cannot exceed the power pin during power-up.

2. T_Ais the “instant on” case temperature.

3. See the last page of this specification for Group A subgroup testing information.

4. 6.0 mA military

5. For test purposes, not more than one output at a time should be shorted. Short circuit test duration should not exceed 30 seconds.
