Description

IC Ground Pin.

RESET goes low if VCC falls below the reset threshold and remains

asserted 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

asserted 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, 3V, 3.3V or 5V.
