Notes:
2.
Minimum voltage equals –2.0V for pulse durations of less than 20 ns.
3.
TA is the “instant on” case temperature.
4.
See the last page for Group A subgroup testing information.
5.
Not more than one output should be shorted at one time. Duration of the short circuit should not exceed 30 seconds.
6.
Inputs are disabled, clock is allowed to run at speed.
