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.
