Programmable Logic Device Pld Procurement Notes

All devices in the GAL16V8 datasheet have been officially discontinued via Product Change Notification PCN#13-10. The GAL16V8D-15LPN is no longer manufactured or distributed by Lattice Semiconductor. Verification of availability requires checking secondary market sources for existing inventory, as direct procurement from the manufacturer is not possible.

Programmable Logic Device Pld Selection Notes

This component provides 16 dedicated inputs and 8 configurable I/O lines within a 20-pin PDIP package. Designers should account for the 15 ns propagation delay and 45 mA typical supply current when selecting this part. The device supports three global OLMC configuration modes: registered, complex, and simple, allowing flexibility in logic implementation.

Programmable Logic Device Pld Part Context

The GAL16V8D series represents Lattice's Generic Array Logic products based on E2CMOS technology. The 'D' suffix indicates the specific device variant within the GAL16V8 family. This series was designed to replace bipolar PAL devices with lower power consumption while maintaining pin-to-pin compatibility.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the discontinuation status. Users requiring equivalent functionality must consult third-party distributors for surplus stock or evaluate modern SPLD alternatives from other manufacturers.
