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. In addition, chip carriers are available for futher reduction in board

space.

All of the register outputs are set to a low level during power up. 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 TIBPAL16’ C series is characterized from 0

°C to 75°C. The TIBPAL16’ M series is characterized for

operation over the full military temperature range of –55

°C to 125°C.

These devices are covered by U.S. Patent 4,410,987.
