Note:

1. These parameters are not 100% tested, but are evaluated at initial characterization and at any time the design is modified where

capacitance may be affected.

SWITCHING CHARACTERISTICS OVER COMMERCIAL AND INDUSTRIAL

Notes:

1. See “Switching Test Circuit” for test conditions.

2. This parameter is tested in standby mode.

4. These parameters are not 100% tested, but are calculated at initial characterization and at any time the design is modified where

frequency may be affected.
