EL4543IUZ-T7

Overview

The EL4543IUZ-T7 is a high-speed differential amplifier manufactured by Renesas Electronics. It features three independent channels within a single integrated circuit, designed for driving twisted-pair transmission lines. The device operates with a gain bandwidth product of 700 MHz and provides a slew rate of 1000 V/us. It supports a supply voltage range from 5 V to 12 V, drawing an operating current of 16.2 mA. Key electrical specifications include a common-mode rejection ratio of 80 dB, a power supply rejection ratio of 70 dB, and a fixed voltage gain of 2 V/V. Each channel delivers an output current of 50 mA. The component is housed in a 24-pin QSOP package and functions as a line driver.

Feature Summary

• Integrates three independent differential amplifier channels for multi-line signal processing
• Provides high-speed performance suitable for twisted-pair transmission applications
• Features fixed voltage gain configuration for simplified circuit design
• Delivers high output drive capability for long-distance signal integrity

Applications

• Driving twisted-pair transmission lines
• High-speed data communication interfaces
• Differential signal distribution systems

Procurement Notes

Verify the specific suffix T7 corresponds to the required reel or cut tape packaging format before ordering. Confirm that the 24-pin QSOP package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with official Renesas documentation to confirm current production status and availability constraints.

Selection Notes

Select this component when a triple-channel differential driver is required for twisted-pair applications. The 700 MHz gain bandwidth and 1000 V/us slew rate support high-frequency signal transmission. The fixed gain of 2 V/V simplifies external resistor networks. Consider the 5 V to 12 V supply range and 16.2 mA current consumption for power budgeting. The QSOP-24 package is suitable for surface-mount assembly processes.

Part Context

This component belongs to the EL4543 series of differential amplifiers produced by Renesas Electronics. The series includes variants such as the EL4543ILZ, which may differ in bandwidth specifications. The EL4543IUZ-T7 specifically denotes the industrial temperature grade version packaged in a reel format. It serves as a specialized line driver within the broader portfolio of analog signal chain products offered by the manufacturer.

Replacement Considerations

The EL4543ILZ is a related variant within the same series but typically exhibits different bandwidth characteristics. Verify pin compatibility and electrical parameters against the EL4543ILZ datasheet before substitution. Other family members may require evaluation of gain stability and drive capability differences.
