GAL22V10D-25LP

Programmable Logic Device Pld Overview

The GAL22V10D-25LP is a discontinued Simple Programmable Logic Device (SPLD) from Lattice Semiconductor, utilizing E2CMOS technology. It features ten Output Logic Macrocells (OLMCs), 22 I/O pins, and a maximum propagation delay of 25 ns. The device operates at a supply voltage of 4.75 V to 5.25 V with a typical operating current of 75 mA. It is housed in a 28-pin Plastic DIP package and supports commercial temperature ranges from 0°C to +75°C.

Programmable Logic Device Pld Feature Summary

• E2CMOS Technology: Electrically erasable floating gate architecture enabling reconfigurable logic with high-speed electrical erase times under 100 ms.
• Ten OLMCs: Provides flexible registered or combinatorial output configurations with individual product-term driven tri-state control.
• Standard Compatibility: Fully function, fuse-map, and parametric compatible with standard bipolar and UVCMOS 22V10 devices.
• Active Pull-ups: Built-in active pull-ups on all pins ensure floating inputs default to a TTL high state.

Programmable Logic Device Pld Procurement Notes

This component is officially discontinued per Product Change Notification PCN#09-10. No new production units are available from the manufacturer. Verification of existing stock should be conducted through authorized distributors or secondary market suppliers, as availability is limited to remaining inventory.

Programmable Logic Device Pld Selection Notes

Select this part only for legacy designs requiring exact pinout and timing compatibility with standard 22V10 architectures. The 25 ns speed grade offers lower performance compared to faster variants like the -4LJ. Ensure the design accommodates the 28-pin Plastic DIP package and commercial temperature specifications.

Programmable Logic Device Pld Part Context
