• Manufacturer Part Number: pallv16v8
• Description: Low Voltage, Zero Power 20-pin Ee Cmos Universal Programmable Array Logic
• Manufacturer: Lattice Semiconductor Corp.

ENDURANCE CHARACTERISTICS
The PALLV16V8 is manufactured using Vantis’ advanced electrically-erasable (EE) CMOS process.
This technology uses an EE cell to replace the fuse link used in bipolar parts. As a result, devices
can be erased and reprogrammed—a feature which allows 100% testing at the factory.
ROBUSTNESS FEATURES
The PALLV16V8 has some unique features that make it extremely robust, especially when operating
in high-speed design environments. Pull-up resistors 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 insensitive to any positive overshoot that has a pulse width of
less than about 100 ns.
