Notes:
1. ICC = ICCQ + 1 mA/MHz × (fSI + fSO)/2
2. TA 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.
