Note 1:
Production testing done at T
A
= +25
°
C; limits over temperature guaranteed by design only.
Note 2:
The device is powered up by the highest voltage between V
BATT
and V
CC
.
Note 3:
MR
input ignores falling input pulses, which occur within the
MR
debounce period (t
DEB
) after a valid
MR
reset assertion.
This prevents invalid reset assertion due to switch bounce.
