T
is the “instant on” case temperature.
3.
See the last page of this specification for Group A subgroup testing information.
4.
For test purposes, not more than one output at a time should be shorted. Short circuit test duration should not exceed 30 seconds.
5.
Tested initially and after any design or process changes that may affect these parameters.
