EL4543IUZ-T13

Overview

The EL4543IUZ-T13 is a high-speed differential line driver manufactured by Renesas Electronics. It integrates three independent channels within a single package, designed for twisted-pair transmission applications. The device features a gain of 2 V/V and operates on a supply voltage ranging from 5 V to 12 V. Key electrical specifications include a gain-bandwidth product of 700 MHz, a slew rate of 1000 V/µs, and a common-mode rejection ratio of 80 dB. Input bias current is specified at -10 µA with an input offset voltage of 10 mV. Each channel provides an output current capability of 50 mA. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Video distribution and display driver circuits

Procurement Notes

Verify the exact suffix against official Renesas documentation, as distributor listings may vary between T7 and T13 packaging variants. Confirm the specific package type and moisture sensitivity level requirements for your assembly process. Check for end-of-life notifications or discontinuation status directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when multiple differential channels are required in a compact surface-mount form factor. Ensure the 700 MHz bandwidth meets the signal frequency requirements of the application. Verify that the 50 mA per-channel drive current is sufficient for the intended load impedance. Consider the QSOP-24 package dimensions for PCB layout constraints.

Part Context

This part belongs to the EL4543 series of differential amplifiers from Renesas Electronics. The series is characterized by high-speed operation suitable for demanding analog signal transmission tasks. The EL4543IUZ variant specifically denotes the integrated unit version in a QSOP package, while the T13 suffix indicates reel packaging. This family supports applications requiring precise differential signal handling with minimal distortion.

Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers. Cross-reference specifications such as gain-bandwidth product, output current, and package dimensions to ensure compatibility. Verify pinout compatibility if replacing with similar differential drivers from other manufacturers.
