Description
Ground.
Active LOW reset. RESET is asserted if V CC falls below the reset threshold and re-
mains low for at least 140 ms after V CC rises above the reset threshold.
Active HIGH reset. RESET is asserted if V CC falls below the reset threshold and re-
mains high for at least 140 ms after V CC rises above the reset threshold.
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 k W pull ? up resistor. The input should be left open if not used.
