Controllers Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number is listed as obsolete or discontinued in available records. Confirm package compatibility with existing PCB footprints, specifically the 14-PDIP form factor. Ensure design updates accommodate the transition to active replacement components if long-term availability is required for production runs.

Controllers Selection Notes

Select this component only if legacy system compatibility with 14-PDIP packaging and 4.5V-5.5V operation is mandatory. Evaluate alternative active memory controllers if future maintenance or scalability is a priority. Verify that the static RAM interface requirements align with the controller's specifications before finalizing the bill of materials.
