Description

Ground

Active LOW reset. RESET is asserted if VCC falls below the reset threshold and

remains low for at least 140 ms after VCC rises above the reset threshold.

Active HIGH reset. RESET is asserted if VCC falls below the reset threshold and

remains high for at least 140 ms after VCC rises above the reset threshold.

Power supply voltage that is monitored.
