These programmable array logic devices feature  
high speed and functional equivalency when  
compared with currently available devices. These  
IMPACT  
circuits  
combine  
the  
latest  
NC – No internal connection  
Pin assignments in operating mode  
AdvancedLow-Power Schottky technology with  
proventitanium-tungstenfusestoprovidereliable,  
high-performance substitutes for conventional  
TTL logic. Their easy programmability allows forquick 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.  
Alloftheregisteroutputsaresettoalowlevelduringpower-up. Extracircuitryhasbeenprovidedtoallowloading  
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.  
These devices are covered by U.S. Patent 4,410,987
