Many µP-based products require manual reset capabil-ity, allowing the operator, a test technician, or externallogic circuit to initiate a reset. A logic low on MRassertsOUT/OUT. OUT/OUTremains asserted while MRis low.This input has an internal 50kΩpullup resistor, so it canbe left open if it is not used. MRcan be driven with TTLor CMOS logic levels, or with open-drain/collector out-puts. Connect a normally open momentary switch fromMRto GND to create a manual reset function. If MRisdriven from long cables or if the device is used in anoisy environment, connect a 0.1µF capacitor from MRto ground to provide additional noise immunity.

Applications InformationInterfacing to Different Logic
Voltage Components
The MAX6408/MAX6411 have an active-low, open-drain output. This output structure will sink currentwhen OUTis asserted. Connect a pullup resistor fromOUTto any supply voltage up to 5.5V (Figure 1). Selecta resistor value large enough to allow a valid logic low(see Electrical Characteristics), and small enough toregister a logic high while supplying all input currentsand leakage paths connected to the OUTline.
