ROBUSTNESS FEATURES
PALCE16V8X-X/5 devices have some unique features
that make them extremely robust, especially when oper-
ating in high-speed design environments. Pull-up resis-
tors on inputs and I/O pins cause unconnected pins to
default to a known state. Input clamping circuitry limits
negative overshoot, eliminating the possibility of false

clocking caused by subsequent ringing. A special noise
filter makes the programming circuitry completely insen-
sitive to any positive overshoot that has a pulse width of
less than about 100 ns for the /5 versions. Selected /4
devices are also being retrofitted with these robustness
features. See chart below for device listings.
