minimum reset pulse width. As MR is TTL/CMOS logic
compatible, it can be driven by an external logic line.
(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
