GAL16V8D-7LJN

Programmable Logic Device Pld Overview

The GAL16V8D-7LJN is a discontinued high-performance E2CMOS PLD from Lattice Semiconductor, utilizing Generic Array Logic architecture. It features eight output logic macrocells with reprogrammable cells and active pull-ups on all pins. The device operates at a maximum propagation delay of 7 ns and supports a maximum frequency of 142.8 MHz. It provides 100% functional testability via preload and power-on reset capabilities for registers. The component includes an electronic signature for identification and is housed in a 20-pin lead-free plastic quad flat package (PLCC).

Programmable Logic Device Pld Procurement Notes

This part number is officially discontinued per Product Change Notification PCN#13-10. Verification of availability requires checking secondary market distributors or authorized liquidation partners such as Rochester Electronics. No new production units are manufactured by Lattice Semiconductor.

Programmable Logic Device Pld Selection Notes

Select this device for designs requiring emulated PAL compatibility with full function and fuse map parity. Ensure the application utilizes the 20-pin PLCC footprint. Verify that the 7 ns speed grade meets timing requirements, noting that registered mode limits dedicated inputs compared to simple or complex configurations.

Programmable Logic Device Pld Part Context

The GAL16V8 series represents Lattice's electrically erasable programmable logic devices based on CMOS technology. The 'D' suffix indicates the specific device variant within the GAL16V8 family, while 'LJ' denotes the low-power PLCC package type. This component bridges the gap between fixed logic gates and modern FPGAs.

Programmable Logic Device Pld Replacement Considerations

No direct public substitute part numbers are listed in the datasheet. Discontinued status implies reliance on obsolete inventory or redesigning with modern CPLD/FPGA equivalents that offer similar pin counts and logic density.
