Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per Product Change Notification PCN#13-10. No new production units are available from Lattice Semiconductor. Verification of authenticity is critical when sourcing from third-party distributors due to the high risk of counterfeits for legacy PLDs. Buyers should confirm the specific lot date code and physical package markings against original datasheet specifications.

Programmable Logic Device Pld Selection Notes

Designers requiring this specific pinout and logic density should verify compatibility with the GAL16V8D-15QP (non-lead-free) if lead content is not a constraint. For modern designs, consider Lattice's MachXO or iCE40 families which offer similar low-power logic capabilities with current support. Ensure compiler software supports the GAL16V8 device type for proper fuse map generation.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents Lattice's Generic Array Logic line, designed to replace discrete TTL/CMOS logic gates. The 'D' suffix indicates the industrial/commercial grade variant using E2CMOS technology, while 'Q' denotes quarter-power consumption and 'PN' specifies the lead-free plastic DIP package. This part was widely used in the 1990s and early 2000s for prototyping and low-volume embedded control.

Programmable Logic Device Pld Replacement Considerations

Direct pin-compatible replacements are limited due to discontinuation. The GAL16V8D-15QP is the non-lead-free equivalent. For functional replacement in new designs, Lattice recommends evaluating the MachXO2 or iCE40 UltraLite families, though these require schematic redesign due to different pinouts and programming interfaces.
