Programmable Logic Device Pld Procurement Notes

Verify the manufacturer origin as National Semiconductor or its successor entities like Texas Instruments, given corporate acquisitions. Confirm the specific suffix 'QS' indicates the required speed grade and package variant. Ensure the datasheet matches the 20 ns delay specification and 20-pin LDCC form factor before procurement.

Programmable Logic Device Pld Selection Notes

Select this part when a GAL16V8 equivalent is needed with a 20 ns speed grade. Compare against GAL16V8-20 variants from other manufacturers if supply chain diversity is required. Ensure the design accommodates the 20-pin LDCC footprint and that the voltage levels match the system's CMOS requirements.

Programmable Logic Device Pld Part Context

This component belongs to the GAL16V8 family of programmable logic devices. It serves as a drop-in replacement for older PAL devices in many designs. The 'QS' suffix typically denotes specific testing or speed binning criteria defined by National Semiconductor for this particular revision.

Programmable Logic Device Pld Replacement Considerations

Check for cross-reference parts such as the Lattice GAL16V8Q-20LVC or Atmel GAL16V8Q-20LVC. Verify pin compatibility and electrical characteristics before substituting with generic GAL16V8-20 equivalents.
