EL1537IREZ

Overview

The EL1537IREZ is a DSL line driver manufactured by Renesas, originally under the Elantec brand. It features two drivers and zero receivers in a 28-HTSSOP package with exposed pad. The device operates on a 12V supply voltage within a temperature range of -40°C to 85°C. It is designed for DSL applications using surface mount installation.

Feature Summary

• Integrated dual-driver architecture optimized for DSL line signaling
• Surface-mount HTSSOP package with exposed thermal pad for efficient heat dissipation
• Designed for operation at standard DSL supply voltages

Applications

• DSL modem line interface circuits
• Digital Subscriber Line transceivers
• Telecommunications equipment requiring DSL signal generation

Procurement Notes

Verify the manufacturer designation as Renesas, which acquired Elantec. Confirm the specific suffix IREZ corresponds to the industrial temperature grade and tape-and-reel packaging format. Ensure compatibility with 28-pin HTSSOP footprints during sourcing.

Selection Notes

Select this component when a dual-channel DSL driver is required for board-level integration. Consider the exposed pad requirement for thermal management and verify that the 12V supply rail matches the system design constraints before implementation.

Part Context

This part belongs to the EL1537 family of DSL interface components. The EL1537 series provides integrated solutions for driving DSL lines, replacing discrete transistor designs. Renesas continues support for these legacy Elantec products in telecommunications markets.

Replacement Considerations

Check for direct pin-compatible replacements within the EL1537 family. Verify if newer Renesas DSL driver families offer improved performance or updated packaging options while maintaining functional equivalence.
