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