Notes:
1. V
IL
(min.) = –2.0V for pulse durations of less than 20 ns.
2. T
A
is the “instant on” case temperature.
3. See the last page of this specification for Group A subgroup testing information.
4. Not more than one output should be shorted at one time. Duration of the short circuit should not exceed 30 seconds.
