Name Description

RESET
MR
V_CC
Ground
Active LOW reset. RESET is asserted if V_CC falls below the reset threshold
and remains low for at least 140ms after V_CC rises above the reset threshold.
Active HIGH reset. RESET is asserted if V_CC falls below the reset
threshold and remains high for at least 140ms 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 140ms after MR returns HIGH. The
active low input has an internal 20kΩ pull-up resistor. The input should be left
open if not used.
Power supply voltage that is monitored.
