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. These are absolute values with respect to device ground and all overshoots due to system or tester noise are included.
4. Tested initially and after any design or process changes that may affect these parameters.
5. Not more than one output should be tested at a time. Duration of the short circuit should not be more than one second. V
OUT
= 0.5V has been chosen to avoid
test problems caused by tester ground degradation.
6. Because these input signals are controlled by product terms, active input polarity may be of either polarity. Internal active input polarity has been shown for
clarity.
