FUNCTION
Ground
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.
Active-High Reset Output. RESET is high while V CC is below the reset threshold. It remains

RESET
high for the reset timeout period after the reset condition is terminated. The reset timeout
period is determined by the SRT input.
