高性能Impact -X PAL电路 HIGH-PERFORMANCE IMPACT-X PAL CIRCUITS

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.
