RESET
Active-LOW, open-drain reset output. RESET remains LOW while V
CC
is below the
reset threshold and for 800ms minimum after V
CC
rises above the reset threshold.
An external pull-up resistor is needed.

RESET
Active HIGH reset output. RESET remains HIGH while V
CC
is below the reset
threshold and for 800ms after V
CC
rises above the reset threshold.

MR
Manual reset input. A negative going edge transition on MR asserts reset. Reset
remains asserted for one reset time-out period (800 ms min). This active-LOW
input has an internal pull-up resistor. It can be driven from a TTL or CMOS logic line
or shorted to ground with a switch. Leave open if unused.
