Notes:

7. 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.

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

9. 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.

10. Parameter included in functional testing.

11. 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.

Test Conditions: VCC = 3V to 3.6V; typical values are at TA = +25°C (Note 9), unless otherwise specified (Note 7). 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. (Continued)
