Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per Product Change Notification (PCN) #13-10 issued by Lattice Semiconductor. Availability is restricted to existing inventory or third-party distributors. Verification of the specific ordering suffix 'J' for PLCC packaging and 'NI' for lead-free industrial grade is required when sourcing replacements.

Programmable Logic Device Pld Selection Notes

Select this part for designs requiring compatibility with standard bipolar or UVCMOS 22V10 devices. Ensure the design accommodates the 15 ns propagation delay limit. Verify that the application environment falls within the specified -40°C to +85°C industrial temperature range and utilizes a 5V power supply.

Programmable Logic Device Pld Part Context

The GAL22V10D series represents a high-performance CMOS alternative to traditional bipolar GAL devices. The 'D' suffix denotes the specific device variant within the GAL22V10 family. This model integrates UltraMOS advanced CMOS technology to reduce power consumption significantly compared to bipolar equivalents while maintaining functional and parametric compatibility.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the discontinued status. Designers should consult Lattice Semiconductor's official obsolescence notices or contact authorized distributors like Rochester Electronics for potential surplus stock options.
