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.

programming information  
Texas Instruments programmable logic devices can be programmed using widely available software and  
inexpensive device programmers.  
The TIBPAL16R4-15M with date codes prior to 9616A must be programmed according to programming  
algorithms/specificationscorrespondingtotheTIBPAL16R4-12C. TheTIBPAL16R4-15Mwithdatecode9616A  
or newer must be programmed according to programming algorithms/specifications corresponding to the  
TIBPAL16R4-10C.  
Regardless of date code, the TIBPAL16L8-15M, TIBPAL16R6-15M, and TIBPAL16R8-15M must be  
programmed according to programming algorithms/specifications corresponding to the TIBPAL16L8-12C,  
TIBPAL16R6-12C, and TIBPAL16R8-12C, respectively. Failure to do so may damage the devices.  
Complete programming specifications, algorithms, and the latest information on hardware, software, and  
firmware are available upon request. Information on programmers capable of programming Texas Instruments  
programmable logic is also available, upon request, from the nearest TI field sales office, local authorized TI  
distributor, or by calling Texas Instruments at (214) 997-5666.
