Hot-selling and scarce PAL20R4ANC Progammable Array Logic IC DIP24 spot stock

Product Descriptions

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.
