description

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.
