GAL18V10B-15LJ

Programmable Logic Device Pld Overview

The GAL18V10B-15LJ is a discontinued High Performance E2CMOS PLD from Lattice Semiconductor. It features a 7.5 ns maximum propagation delay and an Fmax of 111 MHz. The device utilizes Electrically Erasable (E2) floating gate technology for reconfigurable logic with 100% tested yields. It includes ten Output Logic Macrocells (OLMCs) based on the standard 22V10 architecture, supporting registered and combinatorial I/O modes. Key electrical parameters include a typical supply current of 75 mA and TTL-compatible 16 mA outputs.

Programmable Logic Device Pld Procurement Notes

All devices in this datasheet have been officially discontinued per Product Change Notifications PCN#06-07 through PCN#13-10. Verification of availability requires contacting authorized distributors or secondary market suppliers such as Rochester Electronics. No new production units are manufactured by Lattice Semiconductor.

Programmable Logic Device Pld Selection Notes

Select the GAL18V10B-15LJ only if legacy compatibility with the 22V10 macrocell architecture is required. The '15' suffix indicates a 15 ns speed grade, while 'LJ' denotes the PLCC package. Ensure designs account for the discontinuation status and verify that existing programming tools support the E2CMOS process.

Programmable Logic Device Pld Part Context

The GAL18V10 series represents Lattice's Generic Array Logic line built on E2CMOS technology. This specific part number belongs to the commercial grade family, offering a balance of low power consumption and high speed. It serves as a direct pin-compatible replacement for older bipolar GAL devices in existing PCB layouts.

Programmable Logic Device Pld Replacement Considerations

No public confirmed substitute part numbers are listed in the provided documentation. Due to the discontinued status, designers should evaluate modern FPGA alternatives or contact manufacturers for obsolescence management options.
