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