Applications Information
Interfacing to μPs with Bidirectional
Reset Pins
V CC 2 V CC 1
Microprocessors with bidirectional reset pins can inter-
face directly with the open-drain RST output options.

However, conditions might occur in which the push-pull
output versions experience logic contention with the
bidirectional reset pin of the μP. Connect a 10k Ω resis-
tor between RST and the μP’s reset I/O port to prevent

Falling V CC Transients
V CC 2
The MAX6730–MAX6735 μP supervisors are relatively
immune to short-duration falling V CC _ transients (glitch-
es). Small glitches on V CC _ are ignored by the
MAX6730 –MAX6735, preventing undesirable reset
pulses to the μP. The Typical Operating Characteristics
