Procurement Notes

Verify the specific ordering suffix and manufacturing date code upon request. Confirm RoHS status and lead content as this part may contain lead. Ensure the ceramic package integrity matches the application requirements. Request test data or traceability documentation if required for critical systems. Validate that the supplier provides authorized Rochester Electronics stock.

Selection Notes

Select this component when a quad differential driver is required for RS-422 applications. The ceramic package offers superior thermal and mechanical stability compared to plastic variants. Consider the 125 °C maximum operating temperature for harsh environments. Verify pin compatibility with existing PCB layouts designed for CDFP-16 packages.

Part Context

Rochester Electronics specializes in sustaining obsolete and hard-to-find semiconductor products. This component is part of their inventory of licensed and tested devices. The company maintains production of legacy parts that are no longer actively marketed by original manufacturers. This ensures supply continuity for long-life industrial and defense applications.

Replacement Considerations

Direct replacements include other quad RS-422 line drivers in compatible packages. Verify electrical parameters such as output voltage levels and drive current. Check pinout compatibility to ensure direct socket interchangeability without circuit modification.
