Pin Function

1

GND

IC Ground Pin.

2

/RESET

/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 1100ms (minimum) after both VCC exceeds

the supply reset threshold voltage and /MR is deasserted.

3

/MR

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 (1100ms, minimum) 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

20k

Ω resistor. Float if unused.

4

VCC

Power Supply Input.
