Programmable Logic Device Pld Procurement Notes

Verify the specific suffix 'AB' against the manufacturer's official datasheet to confirm voltage range and temperature grade. Confirm that the 28-LJ package designation matches the required footprint. Check for RoHS compliance status as older GAL families may have restricted material declarations.

Programmable Logic Device Pld Selection Notes

Select this component when in-system programming capability is required for GAL22V10 functionality. Compare the 25 ns speed grade against faster alternatives like the ispGAL22LV10 series if higher performance is needed. Ensure the design accommodates the 5V operating voltage requirement of this specific part.

Programmable Logic Device Pld Part Context

This part belongs to the GAL22V10 family, which is functionally compatible with standard bipolar and UVCMOS 22V10 devices. It serves as a drop-in replacement for legacy PAL/GAL designs while adding reprogrammability. The family is known for reducing power consumption by 50% to 75% compared to bipolar equivalents.

Programmable Logic Device Pld Replacement Considerations

Direct functional substitutes include other GAL22V10 variants such as GAL22V10D. For upgraded performance, consider the ispGAL22LV10 series which offers lower voltage operation and faster speeds.
