Input glitch immunity(4)

Corresponds to the actual tSRC

tSRC

Valid for ambient operating temperature: TA = –30 to +85 °C; VCC = 1.65 to 5.5 V (except where noted).

Typical value is at 25 °C and VCC = 3.3 V unless otherwise noted.

Reset outputs are deasserted below 1.575 V typ. and remain deasserted down to VCC = 1 V.

Input glitch immunity is equal to tSRC (when both SR inputs are low), otherwise infinite.
