Procurement Notes

Verify the specific suffix 'JC' against manufacturer documentation to confirm package type and temperature grade. Ensure the source provides traceability to original fabrication data. Confirm RoHS compliance status if required for the target assembly process. Request detailed datasheets to validate pinout configurations before integration into new designs.

Selection Notes

Select this component when a single-channel RS-422 driver is required for high-noise environments. Compare power consumption and propagation delay specifications against system requirements. Verify that the operating voltage range matches the available power supply rails. Consider package availability and thermal performance for the intended enclosure design.

Part Context

Rochester Electronics specializes in sustaining legacy semiconductor products that are no longer actively promoted by original manufacturers. This part belongs to the AMD AM26LS3x family of RS-422 transceivers. The company maintains production through licensed agreements to support long-term industrial applications. This ensures continuity for systems relying on established interface technologies.

Replacement Considerations

Direct equivalents include the Texas Instruments SN75LS193 or the original AMD AM26LS31. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement meets the same RS-422 compliance standards and temperature ratings.
