EL4543IUZS2714

Overview

The EL4543IUZS2714 is a differential amplifier manufactured by Renesas Electronics Corporation, specifically belonging to the EL4543 series. It functions as a high-speed differential twisted pair driver designed for demanding signal transmission applications. The device integrates three independent channels within a single package, providing a gain of 2 V/V. Key electrical specifications include a gain-bandwidth product of 350 MHz and a power supply rejection ratio (PSRR) of 70 dB. It operates on a dual power supply ranging from 5 V to 12 V, with a typical operating current of 16.2 mA. The input bias current is specified at 10 uA, and the input offset voltage is 10 mV. The component supports surface mount installation in a 24-pin QSOP package and is rated for an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates three independent high-speed differential amplifier channels for multi-signal processing.
• Provides fixed unity-gain buffering with a specific gain of 2 V/V for twisted pair drivers.
• Features high power supply rejection ratio to maintain signal integrity under varying supply conditions.
• Designed for surface mount technology with compact packaging suitable for dense circuit boards.

Applications

• High-speed data communication interfaces requiring differential signaling.
• Video distribution systems utilizing twisted pair cable transmission.
• Industrial control systems needing robust noise immunity over long distances.
• Test and measurement equipment requiring precise differential amplification.

Procurement Notes

Verify the exact suffix 'S2714' against official Renesas documentation, as standard listings typically use 'IUZ'. Confirm availability status, as some variants like EL4543ILZ are marked as obsolete. Ensure the supplier provides valid RoHS compliance details and datasheet references matching the specific batch code. Check for moisture sensitivity levels if storage conditions are critical for the assembly process.

Selection Notes

Select this component when a triple-channel differential driver is required for twisted pair applications. The 350 MHz bandwidth suits moderate-speed digital or analog video signals. Compare against single-channel alternatives if pin count reduction is not a priority. Consider the 24-pin QSOP package constraints for PCB layout. Verify that the 5V to 12V supply range aligns with the system's power architecture.

Part Context

The EL4543 series represents Renesas's line of high-performance differential amplifiers, originally developed by Intersil before its acquisition. These devices are engineered to drive balanced loads efficiently while rejecting common-mode noise. The family includes various packages and channel counts, with the IUZ variant offering a quad-small-outline package solution for professional audio and video markets.

Replacement Considerations

Publicly confirmed substitute part numbers for the EL4543IUZS2714 were not found in available sources. Engineers should consult Renesas technical support for direct cross-references or evaluate generic triple-channel differential amplifiers with matching 350 MHz bandwidth and QSOP footprint.
