Manual Reset Input ( MR )
Many F P-based products require manual-reset capabil-
ity, allowing the operator, a test technician, or external
logic circuit to initiate a reset. A logic-low on MR asserts
reset. Reset remains asserted while MR is low, and for
the reset active timeout period (t RP ) or delay (t ON ) after
MR returns high. This input has an internal 50k I pullup
resistor, so it can be left unconnected if it is not used.
MR can be driven with TTL or CMOS logic levels, or
with open-drain/collector outputs. For manual operation,
connect a normally open momentary switch from MR to
GND; external debouncing circuitry is not required. If MR
is driven from long cables or if the device is used in a
noisy environment, connect a 0.1 F F capacitor from MR to

Applications Information
Interfacing to μ P with
Bidirectional Reset Pins
Since RESET on the MAX16074 is open-drain, this
device interfaces easily with F Ps that have bidirectional
reset pins. Connecting the F P supervisor’s RESET output
directly to the F P’s RESET pin with a single pullup resis-
tor allows either device to assert reset (Figure 2).

may typically have when issuing a reset signal. As the
amplitude of the transient increases, the maximum allow-
able pulse width decreases.
