Pin Function
IC Ground Pin.
/RESET goes low if VCC falls below the reset threshold and remains asserted
for one reset timeout period after VCC exceeds the reset threshold.
Manual Reset Input. A logic low on /MR forces a reset. The reset will remain
asserted as long as /MR is held low and for one reset timeout period after /MR goes
high. This input can be shorted to ground via a switch or be driven by TTL or CMOS
logic. Float if unused.
Power Supply Input.
