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.

Products conform to specifications per the terms of Texas Instruments
