Programmable Logic Device Pld Procurement Notes

All devices in this datasheet have been officially discontinued per Product Change Notification (PCN). 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

This component uses the standard 22V10 macrocell architecture for design compatibility. It supports both registered and combinatorial output modes with individually programmable polarity. Designers should verify that the 7.5 ns propagation delay meets system timing requirements and ensure proper power-up reset conditions are met.

Programmable Logic Device Pld Part Context

The GAL18V10 series belongs to the Generic Array Logic family utilizing E2CMOS technology. This specific part number represents the commercial grade version with a -10 speed grade (7.5 ns delay) in a plastic DIP package. It serves as a CMOS-based replacement for older bipolar PAL/GAL devices with lower power consumption.

Programmable Logic Device Pld Replacement Considerations

No direct functional replacements are listed in the official documentation due to the discontinuation status. Designers may need to evaluate modern CPLD or FPGA alternatives from Lattice or other vendors that offer similar pin counts and logic density.
