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 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.
