description
These programmable array logic devices feature high speed and functional equivalency when compared with
currently available devices. These IMPACT-X circuits combine the latest Advanced Low-Power Schottky
technology with proven titanium-tungsten fuses to provide reliable, high-performance substitutes for
conventional TTL logic. Their easy programmability allows for quick design of custom functions and typically
results in a more compact circuit board.
The TIBPAL16’ C series is characterized from 0°C to 75°C. The TIBPAL16’ M series is characterized for
operation over the full military temperature range of –55°C to 125°C.
These devices are covered by U.S. Patent 4,410,987.
