Programmable Logic Device Pld Applications

Programmable Logic Device Pld Procurement Notes

This product is officially discontinued by Lattice Semiconductor Corporation. Verification of availability should focus on obsolete stock or secondary market sources rather than direct manufacturer ordering. Check Product Change Notifications (PCNs) for specific discontinuation dates and last-time-buy information before procurement planning.

Programmable Logic Device Pld Selection Notes

Designers requiring this specific logic density and I/O configuration must account for the discontinued status. Verify that the 28-pin DIP package and 5V operation align with legacy system constraints. Consider modern SPLD replacements if new production is required, ensuring pin compatibility and electrical specifications match the original design requirements.

Programmable Logic Device Pld Part Context

The GAL26CV12 series represents a line of high-performance E²CMOS PLDs from Lattice. These devices were designed to offer significant speed improvements over earlier bipolar PAL equivalents while maintaining low power consumption. The GAL26CV12B-20LJ specifically denotes a 20ns speed grade variant in a plastic DIP package.

Programmable Logic Device Pld Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the discontinued status, engineers should consult Lattice's current CPLD or FPGA portfolios for functional equivalents, verifying pinout and logic capacity manually.
