Pin Function
IC Ground Pin
/RESET goes low if either V
or if /MR is asserted. /RESET remains asserted for one reset timeout period
1100ms min. After both V
/MR is deasserted.
Manual Reset Input. A logic low on /MR forces a reset. The reset will re-
main asserted as long as /MR is held low and for one reset timeout period
(1100ms min.) 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.
