Test Conditions: VCC = 3.0V 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)
