Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per Product Change Notification PCN#13-10. Availability is restricted to existing inventory or secondary market sources. Verification of authenticity and lot date codes is critical when sourcing from non-direct suppliers due to the obsolescence status.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with specific PAL architectures or existing GAL16V8 designs is required. For new designs, consider modern SPLD or CPLD alternatives as this device is no longer in production. Ensure the 25 ns speed grade meets the system timing requirements.

Programmable Logic Device Pld Part Context

The GAL16V8D series represents Lattice's high-performance E2CMOS PLD line. The 'D' suffix denotes the low-power variant, while 'I' indicates the industrial temperature grade. The 'PN' suffix specifies the lead-free Plastic DIP packaging. This device belongs to the broader GAL16V8 family which has been fully phased out.

Programmable Logic Device Pld Replacement Considerations

No direct public substitutes are listed in the provided documentation. As all GAL16V8 devices are discontinued, alternative solutions require evaluating modern programmable logic devices that offer pin-compatible packages or require schematic redesign.
