A Comprehensive Guide To TIFPLA839CFN * Programmable Logic Device (PLD) IC Macrocells

* Programmable Logic Device (PLD) IC Macrocells

General Description

The'FPLA839 (3-stateoutputs) and the 'FPLA840 (open-collector outputs) areTTL field- programmable logic arrays

containing 32 product terms (ANDterms) and six sum terms (OR terms). Each of the sum-of-products output functions

can be programmed either high true or low true. The true condition of each output function is activated by the

programmed logical minterms of 14 input variables. The outputs are controlled by two chip-enable pins to allow output

inhibit and expansion af terms.

These devices provide high-speed data-path logic replacement where several conventional SSI functions can be designed

into a single package.

The 'FPLA839C  and 'FPLA840C are characterized for operation from 0℃ to 70°C.
