Notes:
1.
The voltage on any input or I/O pin cannot exceed the power pin during power-up.
2.
TA is 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.
