Procurement Notes

Verify the specific suffix S2714 against official Renesas documentation to confirm exact packaging or lot traceability details. Confirm availability status as related EL4543 variants may be discontinued. Ensure compatibility with existing QSOP-24 footprints during procurement planning. Request updated lifecycle notifications to mitigate obsolescence risks associated with legacy analog components.

Selection Notes

Select this component when designing circuits requiring multiple differential outputs with matched characteristics. The 350 MHz bandwidth supports applications demanding fast signal transitions. Verify that the 5 V to 12 V supply range aligns with system power constraints. Consider the 16.2 mA quiescent current for thermal management in dense PCB layouts. Ensure the QSOP-24 package fits within the mechanical enclosure constraints.

Part Context

This part belongs to the EL4543 series of differential amplifiers produced by Renesas Electronics, formerly Intersil. The series is characterized by high-speed operation and low distortion, targeting professional audio and video applications. The EL4543 family provides a compact solution for converting single-ended signals to differential formats or driving long cables with balanced signals. It represents a specialized segment of analog signal chain components focused on precision and speed.

Replacement Considerations

Check for direct pin-compatible substitutes such as the EL4543IUZ or EL4543ILZ if the specific S2714 suffix variant is unavailable. Verify that alternative packages maintain the same electrical parameters and thermal performance. Consult Renesas for recommended cross-reference parts to ensure functional equivalence in high-speed differential applications.
