RESET
Active-Low Reset Output.
RESET
is low while V
CC
is below the reset threshold. It remains
low for the reset timeout period after the reset condition is terminated. The reset timeout
period is determined by the SRT input.

RESET
Active-High Reset Output. RESET is high while V
CC
is below the reset threshold. It remains
high for the reset timeout period after the reset condition is terminated. The reset timeout
period is determined by the SRT input.
