*Notice: Stresses beyond those listed under “Absolute Maximun Rat-
ings” may cause permanenet damage to the device. These are stress
ratings only, and functional operation of the device at these or any other
conditions beyond those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximun rating con-
ditions for extended periods may affect device reliability.

RESET push-pull output remains low
while
threshold, and for at least 140 msec
(min.) after
threshold.
RESET push-pull output remains
high while
voltage threshold, and for at least
140 msec (min.) after
above reset threshold.
Manual Reset input generates a
reset when MR is below V
