RESET
Function
Ground
RESET is asserted LOW if V
CC
falls below the reset threshold and remains LOW for the
140ms minimum after the reset conditions are removed. In addition, RESET is active LOW
as long as the manual reset is low.
RESET is asserted HIGH if V
CC
falls below the reset threshold and remains HIGH for the
140ms minimum after the reset conditions are removed. In addition, RESET is active
HIGH as long as the manual reset is low.
Manual Reset Input. A logic LOW on MR asserts RESET. RESET remains active as long
as MR is LOW and for 180ms after MR returns HIGH. The active low input has an internal
20kΩ pull-up resistor. The input should be left open if not used. It can be driven by TTL or
CMOS logic or shorted to ground by a switch..
