Description
IC Ground Pin.
RESET goes low if V CC falls below the reset threshold and remains
asserted for one reset timeout period (140ms min.) after V CC exceeds
the reset threshold.
RESET goes high if V CC falls below the reset threshold and remains
asserted for one reset timeout period (140ms min.) after V CC 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.
