Overview
The EL1537BIREZ is a dual DSL line driver manufactured by Elantec Semiconductor, housed in a 28-pin HTSSOP package. It operates on a single 12V supply and supports data rates up to 19.44 Mbps for ISDN applications. The device integrates two independent drivers with thermal shutdown protection and is rated for industrial temperatures ranging from -40°C to +85°C.
Feature Summary
- Dual integrated DSL line drivers for ISDN transmission
- Thermal shutdown protection for enhanced reliability
- Single 12V power supply operation
Applications
- ISDN terminal adapters
- Digital subscriber line equipment
- Telecommunications interface circuits
Procurement Notes
Verify the manufacturer status as Elantec Semiconductor has undergone corporate restructuring. Confirm current production availability through authorized distributors or Renesas Electronics, which acquired relevant assets. Ensure the specific suffix 'IREZ' matches the required temperature grade and packaging specifications for the target design.
Selection Notes
Select this component for designs requiring dual-channel DSL driving capability within a compact surface-mount footprint. Compare against newer integrated transceivers if higher data rates or lower power consumption are required. Verify that the 28-HTSSOP pinout aligns with existing board layouts and that the 12V supply rail is available in the system architecture.
Part Context
This part belongs to the Elantec DSL driver family, designed specifically for Basic Rate Interface (BRI) ISDN applications. It serves as a discrete solution for line interfacing before the industry consolidated into highly integrated modem chips. The IREZ suffix denotes the industrial temperature range and lead-free HTSSOP packaging.
Replacement Considerations
Direct replacements may be limited due to the legacy status of the EL1537 series. Consider evaluating integrated ISDN transceivers from manufacturers such as Texas Instruments or STMicroelectronics. Verify pin compatibility and electrical characteristics carefully when substituting with modern equivalents.
