APPLICATIONS INFORMATION
Microprocessor Reset
To generate a processor reset, the manual Reset input
allows different reset sources. A pushbutton switch can be
one of these. It is effectively debounced by the 1.0 s
minimum reset pulse width. As MR is TTL/CMOS logic
compatible, it can be driven by an external logic line.

Transient Rejection
The MAX707/708 provides accurate V
CC
monitoring and
reset timing during power–up, power–down, and
brownout/sag conditions, and rejects negative glitches on
the power supply line. Figure 13 shows the maximum
transient duration vs. maximum negative excursion
(overdrive) for glitch rejection. For a given overdrive, the
point of the curve is the maximum width of the glitch
allowed before the device generates a reset signal. Transient
immunity can be improved by adding a capacitor (100 nF for
example) in close proximity to the V
CC
pin of the
MAX707/708.
