Programmable Logic Device Pld Procurement Notes

Verify the manufacturer origin, as this part is originally designed by Texas Instruments but currently supplied by Rochester Electronics as a legacy component. Confirm the specific speed grade suffix (e.g., -5) matches the required timing constraints. Ensure the package type corresponds to the intended PCB footprint. Check for RoHS compliance status if required by current manufacturing standards. Validate the date code and lot traceability for quality assurance purposes.

Programmable Logic Device Pld Selection Notes

Select the -5 speed grade only if the system timing budget requires a maximum 5 ns propagation delay. Choose this registered variant over combinatorial versions when output latching is necessary to synchronize data. Verify that the 20-pin package format fits the available board space. Consider the extended temperature range suitability for harsh environments compared to commercial grade parts.

Programmable Logic Device Pld Part Context

This component is part of the Texas Instruments PAL16R8 family of Programmable Array Logic devices. These circuits are widely used in legacy digital designs requiring fixed-function logic replacement or custom logic implementation. Rochester Electronics provides these parts as authorized distributors of excess inventory or long-term supply agreements for discontinued TI products.

Programmable Logic Device Pld Replacement Considerations

Direct pin-to-pin replacements include other PAL16R8 variants with compatible speed grades and packages, such as the PAL16R8-5JC or PAL16R8-10JC. Verify logical equivalence before substitution, as programming configurations may differ. Cross-reference with National Semiconductor equivalents if original TI sources are unavailable.
