Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters. • Functionally Equivalent to the TIBPAL22V10/10A, with Additional Feedback Paths in the Output Logic Macrocell • Choice of Operating Speeds: TIBPAL22VP10-20C . . . 20 ns Max TIBPAL22VP10-25M . . . 25 ns Max • Variable Product Term Distribution Allows More Complex Functions to Be Implemented • Each Output Is User Programmable for Registered or Combinational Operation, Polarity, and Output Enable Control • TTL-Level Preload for Improved Testability • Extra Terms Provide Logical Synchronous Set and Asynchronous Reset Capability • Fast Programming, High Programming Yield, and Unsurpassed Reliability Ensured Using Ti-W Fuses • AC and DC Testing Done at the Factory Utilizing Special Designed-In Test Features • Dependable Texas Instruments Quality and Reliability • Package Options Include Plastic Dual-In-Line and Chip Carrier Packages description The TIBPAL22VP10’ is equivalent to the TIBPAL22V10A but offers additional flexibility in the output structure. The improved output macrocell uses the registered outputs as inputs when in a high-impedance condition. This provides two additional output configurations for a total of six possible macrocell configurations all of which are shown in Figure 1. These devices contain up to 22 inputs and 10 outputs. They incorporate the unique capability of defining and programming the architecture of each output on an individual basis. Outputs may be registered or nonregistered and inverting or noninverting. In addition, the data may be fed back into the array from either the register or the I/O port. The ten potential outputs are enabled through the use of individual product terms. Further advantages can be seen in the introduction of variable product term distribution. This technique allocates from 8 to 16 logical product terms to each output for an average of 12 product terms per output. This variable allocation of terms allows far more complex functions to be implemented than in previously available devices.
