Description
Ground
Active LOW reset. RESET is asserted if V_CC falls below the reset threshold and
remains low for at least 140 ms after V_CC rises above the reset threshold.
Active HIGH reset. RESET is asserted if V_CC falls below the reset threshold and
remains high for at least 140 ms after V_CC rises above the reset threshold.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
