NOTES:

8. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise

specified.

9. Parameters with MIN and/or MAX limits are 100% tested at -55°C, +25°C, and +125°C, unless otherwise specified.

10. Typical values are at 3.3V. Parameters with a single entry in the “TYP” column apply to 3.3V. Typical values shown are not guaranteed.

11. Parameter included in functional testing.

12. Performed during the 100% screening operations across the full operating temperature range. Not performed as part of TCI Group E and Group C.

Radiation characterization testing performed as part of the initial release and any major changes in design.

Electrical Specifications Test Conditions: VCC = 3.0V to 3.6V; typicals are at TA = +25°C (Note 10), unless otherwise specified (Note 8).

Boldface limits apply across the operating temperature range, -55°C to +125°C; over a total ionizing dose of 75krad(Si) at +25°C with exposure at a low

dose rate of <10mrad(Si)/s.; and over a total ionizing dose of 100krad(SI) at +25°C with exposure of a high dose rate of 50krad(SI)/s to 300krad(SI)/s.
