Programmable Logic Device Pld Procurement Notes

This component has been officially discontinued by Lattice Semiconductor per Product Change Notification PCN#09-10. Availability is restricted to existing inventory or third-party distributors. Verification of the specific manufacturing lot and authenticity is required due to the end-of-life status.

Programmable Logic Device Pld Selection Notes

Select this part only if legacy compatibility with standard bipolar or UVCMOS 22V10 devices is mandatory. The -25 speed grade provides a 25 ns maximum propagation delay. Ensure the design accommodates the 5 V supply voltage range of 4.75 V to 5.25 V for commercial grade operation.

Programmable Logic Device Pld Part Context

The GAL22V10D-25QP belongs to the GAL22V10D product line, which represents high-performance Electrically Erasable Programmable Logic Devices. This series was designed to replace older bipolar logic families while offering reprogrammability through E2CMOS technology.

Programmable Logic Device Pld Replacement Considerations

Public confirmed substitute part numbers are not available as the entire GAL22V10 family has been discontinued.
