EL4543ILZ-T7S2714

Overview

The EL4543ILZ-T7 is a high-speed differential line driver manufactured by Renesas Electronics, formerly Intersil. It features three independent channels designed for driving twisted-pair transmission lines. The device operates with a gain bandwidth product of 350 MHz and supports supply voltages ranging from 5 V to 12 V. Key electrical specifications include an input bias current of 10 uA, an input offset voltage of 10 mV, and a quiescent operating current of 16.2 mA. It provides a fixed voltage gain of 2 V/V and offers a power supply rejection ratio of 70 dB. The component is housed in surface-mount packages and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides three independent differential output channels for simultaneous signal transmission
• Engineered for high-frequency performance with a 350 MHz gain-bandwidth product
• Features low input bias current and low input offset voltage for signal integrity
• Includes high power supply rejection ratio to minimize noise interference

Applications

• Driving twisted-pair transmission lines in communication systems
• High-speed digital signal distribution interfaces
• Differential line driver circuits requiring multiple channels

Procurement Notes

Verify the exact suffix designation against official Renesas documentation, as standard listings typically reference EL4543ILZ-T7 or EL4543ILZ-T13. Confirm package type compatibility and check for end-of-life status, as this series may be discontinued. Ensure the specific reel quantity matches project requirements when sourcing from distributors.

Selection Notes

Select this component when a multi-channel differential driver is required for twisted-pair applications. Consider the 350 MHz bandwidth limit for signal frequency requirements. Verify that the 5 V to 12 V supply range aligns with system power rails. Check if the fixed 2 V/V gain meets interface impedance matching needs without additional external components.

Part Context

The EL4543 belongs to the EL4543 family of differential amplifiers produced by Renesas Electronics through its acquisition of Intersil. These devices are specialized for high-speed data transmission over balanced lines. The T7 suffix typically indicates tape and reel packaging for automated assembly, distinguishing it from other packaging options like tubes or cut tape.
