GAL16V8D-15LJ

Programmable Logic Device Pld Overview

The GAL16V8D-15LJ is a discontinued Simple Programmable Logic Device (SPLD) manufactured by Lattice Semiconductor. It utilizes high-performance E2CMOS technology to achieve a maximum propagation delay of 15 ns and a maximum operating frequency of 45.5 MHz. The device features an architecture with 16 inputs and 8 outputs, powered by a single 5V supply. It incorporates Electrically Erasable floating gate technology, allowing for rapid reprogramming with erase times under 100 ms and data retention exceeding 20 years.

Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued per Product Change Notification PCN#13-10. No new units are available from the manufacturer. Verification of availability requires checking third-party distributors for existing inventory or contacting authorized liquidation partners such as Rochester Electronics.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with specific PAL fuse maps is required. The GAL16V8D emulates various 20-pin PAL architectures including 16R8, 16L8, and 10L8. Designers should account for the 15 ns speed grade when calculating system timing margins and ensure the PLCC package fits the target footprint.

Programmable Logic Device Pld Part Context

The GAL16V8D-15LJ belongs to the GAL16V8 family of Generic Array Logic devices. The 'D' suffix indicates the use of E2CMOS technology, while '15' specifies the 15 ns speed grade. The 'LJ' suffix denotes the Plastic Leadless Chip Carrier (PLCC) package variant within the commercial grade product line.
