Procurement Notes

Verify the manufacturer origin as National Semiconductor or its successor entities when sourcing components. Confirm the specific suffix 'N' indicates the correct package type and temperature range as per official datasheets. Ensure compatibility with system voltage levels and interface requirements before integration into final designs.

Selection Notes

Select this component when multiple differential receivers are needed in a compact form factor. Consider the quad configuration for cost-effective space-saving designs. Verify that the RS-422/RS-423 protocol support aligns with the system's communication standards. Evaluate power consumption and operating temperature range against application constraints.

Part Context

This component belongs to the family of high-speed line receivers from National Semiconductor. It complements other transmitters and receivers in serial communication solutions. The quad architecture allows for simplified board layout compared to using individual single receivers. It serves as a key building block for multi-channel serial data acquisition systems.

Replacement Considerations

Check for direct pin-to-pin replacements from National Semiconductor or acquired companies like Texas Instruments. Verify electrical parameters such as propagation delay and input sensitivity match the original specifications. Ensure the replacement supports both RS-422 and RS-423 modes if required by the design.
