These programmable array logic devices feature high speed and functional equivalency when compared with currently available devices. These IMPACT-XTM 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 TIBPAL20' C series is characterized from 0C to 75C. The TIBPAL20' M series is characterized for operation over the full military temperature range of 55C to 125C.
