Valid for ambient operating temperature: TA = –40 to +85 °C; VCC = 1.0 V to 5.5 V (except where noted). 2. Typical value is at 25 °C and VCC = 3.3 V unless otherwise noted. 3. For devices with VRST < 3.0 V. 4. Guaranteed by design. 5. Input glitch immunity is equal to tSRC (when both SR inputs are low), otherwise infinite. Table 5.
