GND
Ground

—
RESET
Active LOW reset. RESET
is asserted if VCC falls below the reset threshold
and remains low for at least 140ms after VCC rises above the reset threshold.
—
2
RESET
Active HIGH reset. RESET is asserted if VCC falls below the reset threshold
and remains high for at least 140ms after VCC rises above the reset
threshold.
3
MR
Manual Reset Input. A logic LOW on MR
asserts RESET. RESET remains
active as long as MR
is LOW and for 140ms after MR
returns HIGH. The
active low input has an internal 20k pull-up resistor. The input should be
left open if not used.
4
VCC
Power supply voltage that is monitored.
