MAX6316M/MAX6318MH/MAX6319MH:
Bidirectional, Active-Low, Reset Output.
Intended to interface directly to microprocessors
with bidirectional resets such as the Motorola
68HC11.
MAX6316L/MAX6318LH/MAX6319LH:
Active-Low, Reset Output. CMOS push/pull
output (sources and sinks current).
MAX6320P/MAX6321HP/MAX6322HP:
Open-Drain, Active-Low, Reset Output. NMOS out-
put (sinks current only). Connect a pull-up resistor
from RESET to any supply voltage up to 6V.
Active-High, Reset Output. CMOS push/pull output
(sources and sinks current). Inverse of RESET.
Ground
Active-Low, Manual Reset Input. Pull low to force a
reset. Reset remains asserted for the duration of
the Reset Timeout Period after MR transitions from
low to high. Leave unconnected or connected to
V
Watchdog Input. Triggers a reset if it remains
either high or low for the duration of the watchdog
timeout period. The internal watchdog timer clears
whenever a reset asserts or whenever WDI sees a
rising or falling edge. To disable the watchdog fea-
ture, leave WDI unconnected or three-state the dri-
ver connected to WDI.
