TIBPAL20R8-25CFN Datasheet PDF - TI

●description

●These programmable array logic devices feature high speed and functional equivalency when compared with currently available devices. These IMPACT™ circuits combine the latest AdvancedLow-Power Schottky technology with proven titanium-tungsten fuses to provide reliable, high-performance substitutes for conventional TTL logic. Their easy programmability allows forquick design of custom functions and typically results in a more compact circuit board. In addition, chip carriers are available for futher reduction in board space.
