These IMPACT™ circuits bine 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 pact circuit board. In addition, chip carriers are available for futher reduction in board space. TIBPAL20L8’ C SUFFIX . . . JT OR NT PACKAGE M SUFFIX . . .
