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 further
reduction in board space.
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.
