Description

Ground Reference for All Signals; 0 V.

Active High Logic Output. RESET remains high while VCC is below the reset threshold

and remains high for 240 ms (typical) after VCC rises above the reset threshold.

Active Low Logic Output. RESET remains low while VCC is below the reset threshold

and remains low for 240 ms (typical) after VCC rises above the reset threshold.

Supply Voltage Being Monitored.
