The area below the curves of the graph is the region in
which these devices typically do not generate a reset
pulse. This graph was generated using a falling pulse
applied to VCC, starting above the actual reset thresh-
old (VTH) and ending below it by the magnitude indicat-
ed (reset threshold overdrive). As the magnitude of the
transient increases (VCC goes further below the reset
threshold), the maximum allowable pulse width
decreases. Typically, a VCC transient that goes 100mV
below the reset threshold and lasts 20s or less does
not cause a reset pulse to be asserted.
