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.

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 and over a total ionizing dose of 75krad(Si) at +25°C with exposure at

a low dose rate of <10mrad(Si)/s. (Continued)
