GND 1 3 3 Ground
Manual reset. Pull this pin to a logic low to assert the RESET
MR N/A N/A 2 output. After the MR pin is deasserted, the RESET output
deasserts after the reset delay (t
d
) elapses.
NC N/A 2 N/A No internal connection.
Active-low reset output. RESET has a push-pull output drive and is
capable of directly driving input pins. RESET is low as long as V
