Notes:
1. T
A
is the “instant on” case temperature.
2. See the last page of this specification for Group A subgroup testing information.
3. V
IL
(min.) = –3.0V for pulse durations less than 30 ns.
4. Not more than 1 output should be shorted at one time. Duration of the short circuit should not exceed 30 seconds.
5. Tested initially and after any design or process changes that may affect these parameters.
