______________________________________________________________Pin Description
PIN NAME
FUNCTION
1
GND Ground
2
RESET
Active-Low Open-Drain Output. Connect to an external pull-up resistor. Can be pulled up to a voltage
higher than VCC, but less than 6V.
3
MR
Manual Reset Input. A logic low on MR asserts reset. Reset remains asserted as long as MR is low, and
for the reset timeout period (tRP) after the reset conditions are terminated. Connect to VCC if not used.
4
VCC
Supply Voltage and Reset Threshold Monitor Input
