CAPACITANCE (Note 1)
Note:
1. These parameters are not 100% tested, but are evaluated at initial characterization and at any time the design is modified
SWITCHING CHARACTERISTICS over COMMERCIAL and INDUSTRIAL operating ranges
(Note 2)
Notes:
2. See Switching Test Circuit for test conditions.
3. These parameters are not 100% tested, but are calculated at initial characterization and at any time the design is modified
6. t CF is a calculated value and is not guaranteed. t CF can be found using the following equation:
