Notes:
2. TA is the “instant on” case temperature.
3. See the last page of this specification for Group A subgroup testing information.
4. VIL (Min.) = –2.0V for pulse durations of less than 20 ns.
5. For test purposes, not more than one output at a time should be shorted. Short circuit test duration should not exceed 30 seconds.
