Description for the TIBPAL20R8-20M
These programmable array logic devices feature high speed and functional equivalency when compared with currently available devices. These IMPACT™ 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. In addition, chip carriers are available for futher reduction in board space.
Extra circuitry has been provided to allow loading of each register asynchronously to either a high or low state. This feature simplifies testing because the registers can be set to an initial state prior to executing the test sequence.
The TIBPAL20’ C series is characterized from 0°C to 75°C. The TIBPAL20’ M series is characterized for operation over the full military temperature range of ’55°C to 125°C.
