Pin Function
IC Ground Pin
/RESET goes low if VCC falls below the reset threshold and remains as-
serted for one reset timeout period (140ms min.) after VCC exceeds the reset
threshold
RESET goes high if VCC falls below the reset threshold and remains as-
serted for one reset timeout period (140ms min.) 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 (140ms
min.) after /MR goes high. This input can be shorted to ground via a switch
or driven from CMOS or TTL logic. Float if unused.
Power Supply Input.
