Programmable Logic Device Pld Procurement Notes

Verify RoHS compliance status as historical data indicates non-compliance for this specific part number. Confirm manufacturer origin, as production rights have transferred between AMD, National Semiconductor, and Texas Instruments. Ensure the 'A4' suffix corresponds to the required speed grade or package variant for your specific design requirements.

Programmable Logic Device Pld Selection Notes

Select this component when registered output functionality is required for synchronous logic designs. Compare against PAL16R8 variants if different propagation delays or pinout configurations are needed. Ensure the 20-pin QCCJ package fits the PCB footprint constraints. Verify voltage level compatibility with existing TTL circuitry.

Programmable Logic Device Pld Part Context

This device belongs to the PAL Series 24 family, which includes related parts like PAL16R8, PAL16L8, and PAL16R6. These devices were originally developed by Advanced Micro Devices and later supported by National Semiconductor and Texas Instruments under the IMPACT PAL series lineage. The PAL16R8A4CNL represents a specific speed and package configuration within this widely used programmable logic family.

Programmable Logic Device Pld Replacement Considerations

Direct substitutes include PAL16R8-25PC or PAL16R8-25QC from Advanced Micro Devices. Cross-manufacturer equivalents may be found among Texas Instruments or Lattice Semiconductor PAL devices, but pinouts and electrical characteristics must be verified. PAL16R8ACNL is a similar variant with potential differences in speed grade.
