RECOMMENDED OPERATING CONDITIONS

DC ELECTRICAL CHARACTERISTICS (Pre/Post-Radiation)*

(V

Notes:

* Post-radiation performance guaranteed at 25

°C per MIL-STD-883 Method 1019 at 1E6 rad(Si).

1. Measured only for initial qualification, and after process or design changes that could affect input/output capacitance.

2. Supplied as a design limit but not guaranteed or tested.

3. Not more than one output may be shorted at a time for maximum duration of one second.

4. Functional test.

5. Derates at 3.0mA/MHz.
