82V2082PF

Overview

The 82V2082PF is a discontinued dual-channel Line Interface Unit (LIU) from Renesas Electronics, designed for E1/T1/J1 telecommunications applications. It supports both long-haul and short-haul transmission modes within a single integrated circuit. The device operates on a 3.3 V power supply with a specified range of 3.13 V to 3.47 V. It is housed in an 80-lead Thin Quad Flat Package (TQFP) measuring 14x14 mm. The component functions as a telecom interface IC, providing the necessary physical layer connectivity for digital carrier systems.

Feature Summary

• Dual-channel architecture supporting simultaneous E1, T1, or J1 line interfacing
• Integrated Long Haul and Short Haul LIU functionality for flexible deployment
• Surface-mount installation in an 80-TQFP package for compact board integration

Applications

• E1/T1/J1 digital carrier system line interfaces
• Telecommunications network equipment requiring dual LIU channels
• Long-haul and short-haul transmission terminal units

Procurement Notes

This part number is officially obsolete and no longer manufactured by Renesas Electronics. Verification should focus on identifying active replacement components rather than sourcing the original unit. Check manufacturer notices for direct substitutes such as the 82V2082PFG. Ensure any alternative selection maintains compatibility with existing 80-TQFP footprints and 3.3 V logic levels.

Selection Notes

Designers must transition to supported alternatives due to the discontinuation status of this specific model. The 82V2082PFG is listed as a direct replacement option. Evaluate pinout compatibility between the legacy 80-TQFP and the new package variant. Confirm that the substitute meets the required 3.3 V operating voltage and dual-channel LIU specifications for the target application.

Part Context

The 82V2082PF belongs to the 82V2082 series of telecom interface ICs. It serves as a predecessor to newer packaging variants like the PFG. The component was widely used in standard digital telephony infrastructure before being phased out. Its discontinuation reflects the natural lifecycle management of legacy telecom interface solutions by the manufacturer.

Replacement Considerations

The 82V2082PFG is identified as a direct replacement. Verify package dimension differences between the PF and PFG suffixes to ensure mechanical fit.
