Active HIGH reset. RESET is asserted if V
mains high for at least 140 ms after V
Active LOW reset. RESET is asserted if V
mains low for at least 140 ms after V
Manual Reset Input. A logic LOW on MR asserts RESET. RESET remains active as
long as MR is LOW and for 140 ms after MR returns HIGH. The active low input has
an internal 20 kW pull−up resistor. The input should be left open if not used.
