RESET push-pull output remains
low while V DD is below the reset
voltage threshold and for 140 msec
(min.) after V DD rises above reset
threshold
V DD
ELECTRICAL CHARACTERISTICS
V DD = Full Range, T A = Operating Temperature Range, unless otherwise noted. Typical values are at T A = +25°C,
V DD = 5V for L/M/J, 3.3V for T/S, 3.0V for R and 2.5V for Z (Note 1) .
