82V2048DA

Overview

The 82V2048DA is an octal T1/E1 Line Interface Unit (LIU) manufactured by Renesas Electronics. It operates on a single 3.3 V power supply with a voltage range of 3.13 V to 3.47 V and draws 55 mA of operating current. The device supports both parallel and serial interfaces for data transmission. It is housed in a 144-pin TQFP package designed for surface mount installation. The component functions within a commercial temperature range from -40°C to +85°C and is classified as moisture sensitive.

Feature Summary

• Integrates eight independent line interface channels for T1, E1, or J1 short-haul applications
• Supports flexible digital interface connectivity via parallel and serial modes
• Designed for low-power operation using a standard 3.3 V supply

Applications

• T1/E1/J1 short-haul line interface units
• Telecommunications network equipment
• Digital subscriber line access multiplexers

Procurement Notes

Verify the specific suffix 'DA' against official Renesas documentation to confirm pinout and packaging details. Confirm RoHS compliance status through the manufacturer's latest datasheet, as legacy variants may differ. Check for End-of-Life notifications or Product Change Notices that may affect long-term availability and manufacturing continuity.

Selection Notes

Select this component for designs requiring integrated octal line driving capabilities without external transceivers. Ensure the PCB layout accommodates the 144-pin TQFP footprint and thermal requirements. Verify that the system power supply strictly maintains the 3.13 V to 3.47 V window to guarantee signal integrity and proper LIU operation.

Part Context

This part belongs to the 82V2048 family of telecom interface ICs. It serves as a direct replacement for the IDT82V2048DAG under Renesas branding following the acquisition of Integrated Device Technology. The device consolidates multiple line driver functions into a single chip to reduce board space and complexity in telecommunications infrastructure.

Replacement Considerations

The IDT82V2048DAG is a confirmed equivalent part number for this component. Verify pin compatibility and electrical specifications before substitution.
