GAL16V8D-7LJNI

Programmable Logic Device Pld Overview

The GAL16V8D-7LJNI is a discontinued high-performance Electrically Erasable CMOS (E2CMOS) programmable logic device from Lattice Semiconductor. It features an 8-output Generic Array Logic architecture with reconfigurable Output Logic Macrocells (OLMCs). The -7 speed grade specifies a maximum propagation delay of 3.5 ns and a maximum operating frequency of 250 MHz. The device utilizes UltraMOS technology, offering active pull-ups on all pins and low power consumption typical of 75 mA. It supports registered, complex, and simple modes for flexible logic implementation.

Programmable Logic Device Pld Procurement Notes

All devices in the GAL16V8 datasheet have been officially discontinued via Product Change Notifications (PCNs), including PCN#13-10 which references this part. No new production is available from Lattice Semiconductor. Verification of availability requires checking third-party distributors for existing stock or contacting authorized liquidation partners such as Rochester Electronics for potential inventory.

Programmable Logic Device Pld Selection Notes

Select the GAL16V8D-7LJNI only if legacy compatibility with specific PAL fuse maps or parametric characteristics is required. The 'I' suffix denotes Industrial Grade (-40°C to +85°C), 'J' indicates PLCC package, 'N' signifies lead-free construction, and '7' represents the 3.5 ns speed grade. Ensure design tools support the GAL16V8 device type for proper OLMC configuration.

Programmable Logic Device Pld Part Context

This component belongs to the GAL16V8 family, which combines high-speed CMOS processes with E2 floating gate technology. The D variant indicates the specific generation within the GAL series. The device provides full function/fuse map/parametric compatibility with standard 20-pin PAL devices, allowing it to serve as a drop-in replacement for older bipolar logic designs while offering reprogrammability.

Programmable Logic Device Pld Replacement Considerations

As the GAL16V8D-7LJNI is discontinued, direct functional replacements are limited. Designers may consider modern CPLDs or FPGAs from Lattice (e.g., MachXO series) or other vendors, but these require architectural redesign. For exact pin-to-pin and logic-equivalent replacement, contact Rochester Electronics regarding available surplus inventory.
