Programmable Logic Device Pld Procurement Notes

This part number is officially discontinued per Product Change Notification PCN#09-10. No new production units are available from Lattice Semiconductor. Verification of availability requires checking third-party distributors for existing inventory or obsolete stock. Designers should consider replacement strategies due to the end-of-life status.

Programmable Logic Device Pld Selection Notes

Select this component only if legacy compatibility with standard bipolar or UVCMOS 22V10 devices is required. The -20 speed grade offers a 20 ns maximum propagation delay. Ensure the application fits the commercial temperature range (0°C to +75°C) and 5V supply requirements. Verify that the 24-pin PDIP package form factor matches the target PCB layout constraints.

Programmable Logic Device Pld Part Context

The GAL22V10D series represents a high-performance CMOS alternative to older bipolar 22V10 devices, offering significant power reduction while maintaining functional and parametric compatibility. The 'D' suffix denotes the specific device variant within the GAL22V10 family. This generation of SPLDs was widely used before the transition to more complex CPLD and FPGA architectures.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Due to the discontinued status, designers must evaluate modern Lattice ispGAL or MachXO families for functional equivalents, ensuring pinout and logic density compatibility.
