EL1537IRE

Overview

The EL1537IRE is a dual DSL line driver manufactured by Elantec, now part of Renesas. It operates on a single 12V supply and supports the DSL protocol with two drivers and zero receivers. The device is housed in a 28-HTSSOP package with an exposed pad, featuring surface-mount installation. It is rated for operation within a temperature range of -40°C to 85°C.

Feature Summary

• Integrated dual driver architecture designed specifically for DSL applications
• Single voltage supply operation simplifying power management
• Surface-mount packaging with exposed thermal pad for efficient heat dissipation

Applications

• DSL modem line interface circuits
• Digital subscriber line transceivers
• Telecommunications equipment requiring DSL signal driving

Procurement Notes

Verify the manufacturer designation as Elantec or Renesas depending on the production era. Confirm the package type matches the 28-HTSSOP specification with an exposed pad. Ensure the operating temperature range meets the required environmental conditions for the target application.

Selection Notes

Select this component when a dedicated dual DSL driver is required for line interfacing. Consider the 28-pin HTSSOP footprint for PCB layout constraints. Verify compatibility with the specific DSL standard being implemented in the design.

Part Context

This component belongs to the Elantec/Renesas family of DSL interface devices. It serves as a specialized driver for digital subscriber line applications, distinct from general-purpose operational amplifiers or logic drivers found in other product lines.

Replacement Considerations

Check for direct pin-compatible replacements within the Renesas portfolio. Verify that any substitute maintains the same 28-HTSSOP package and 12V supply requirement. Ensure the alternative device supports the same DSL protocol specifications.
