Manual Reset Input. A logic low on MR asserts reset. Reset remains asserted as long as MR is low, and for
the reset timeout period (t
RP
) after the reset conditions are terminated. Connect to V
CC
if not used.

PIN
Active-Low Complementary Output. In addition to the normal n-channel pulldown, RESET has a p-channel
pullup transistor in parallel with a 4.7kΩ resistor to facilitate connection to µPs with bidirectional resets. See
the Reset Output section.
