Pin Function

IC Ground Pin

/RESET goes low if either VCC falls below the supply reset threshold voltage

or if /MR is asserted. /RESET remains asserted for one reset timeout period

after both VCC exceeds the supply reset threshold voltage and /MR is deas-

serted.

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 driven

from CMOS or TTL logic. Pulled high internally through a 20kΩ resistor. Float

if unused.

Power supply Input.
