Procurement Notes

Verify the manufacturer part number against official Renesas documentation to ensure authenticity. Confirm that the specific suffix corresponds to the required packaging and temperature grade. Check for any product change notices or end-of-life announcements prior to procurement. Ensure compatibility with existing system power supplies and interface requirements.

Selection Notes

Select this component when designing systems requiring multiple T1/J1/E1 short-haul connections in a compact form factor. Verify that the 128-pin LQFP footprint fits the PCB layout constraints. Ensure the design accommodates the specified 3.3 V nominal supply voltage and thermal dissipation requirements for the target operating environment.

Part Context

This component belongs to the Renesas 82V2044 family of telecom interface ICs. It serves as a high-density solution for integrating multiple line interface units into a single package. The device replaces discrete solutions, reducing board space and simplifying the design of short-haul telecommunications networks.

Replacement Considerations

Consult official Renesas documentation for verified cross-reference part numbers. Ensure any substitute maintains identical pinout, electrical characteristics, and interface protocols.
