82V2042EPF8

Overview

The 82V2042EPF8 is a dual Line Interface Unit (LIU) manufactured by Renesas Electronics, designed for T1/E1/J1 short-haul telecommunications applications. It operates on a single 3.3 V supply voltage with a specified range of 3.13 V to 3.47 V. The device integrates two independent channels within a compact surface-mount package. It supports both parallel and serial interface configurations to facilitate connection with digital signal processors or transceivers. The component is engineered for high reliability in telecom infrastructure environments.

Feature Summary

• Dual-channel architecture supporting simultaneous T1, E1, and J1 line interfacing
• Integrated LIU functionality for short-haul transmission systems
• Flexible interface options including parallel, serial, and JTAG support

Applications

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

Procurement Notes

Verify current availability status directly with the manufacturer or authorized distributors, as supply constraints may apply. Confirm RoHS compliance requirements against specific project standards, noting that some listings indicate non-compliance while others suggest variations based on production date. Ensure ordering suffixes match exact package and tape specifications required for automated assembly processes.

Selection Notes

Select this component for designs requiring dual-channel short-haul LIU capabilities with 3.3 V operation. Compare channel count and interface flexibility against alternatives like the 82V2044EPF8 if octal configuration is needed. Verify thermal performance and package dimensions against PCB layout constraints. Ensure compatibility with system clocking requirements for T1/E1/J1 signaling standards.

Part Context

This part belongs to the 82V20xx series of telecom interface ICs from Renesas, formerly IDT. It serves as a specialized solution for line interfacing in digital telephony networks. The EPF8 suffix typically denotes a specific reel packaging format. Related parts in the family include the 82V2042PFG8 and other variants offering different channel counts or long-haul capabilities.

Replacement Considerations

The 82V2042PFG8 is a pin-compatible alternative in tray packaging. For higher channel density, consider the 82V2044EPF8 octal LIU. Verify functional equivalence regarding interface protocols and electrical characteristics before substitution.
