UCC5511PM

Overview

The UCC5511PM is a low-voltage differential (LVD) terminator integrated circuit designed for SCSI bus applications. It operates within a supply voltage range of 2.7V to 5.25V and supports up to 27 terminations. The device is housed in a 64-LQFP surface-mount package and functions within an operating temperature range of 0°C to 70°C. This component serves as a signal terminator to maintain signal integrity on high-speed data lines.

Feature Summary

Integrated LVD termination solution for SCSI interfaces
Supports multiple termination points via single IC
Surface-mount packaging for automated assembly

Applications

SCSI bus signal termination
Low-voltage differential signaling circuits
High-speed digital interface protection

Procurement Notes

Verify the obsolete status before procurement planning, as availability may be limited. Confirm that the 64-LQFP package dimensions match the target PCB layout. Ensure the 2.7V to 5.25V supply range aligns with the system design requirements. Check for alternative sources if new production units are unavailable.

Selection Notes

Select this component specifically for LVD SCSI termination needs requiring a 64-pin form factor. Consider the 0°C to 70°C commercial temperature range suitability. Evaluate the 27-termination capacity against bus load requirements. Verify compatibility with 2.7V to 5.25V logic levels.

Part Context

The UCC5511PM belongs to the Unitrode family of interface components, specifically targeting legacy SCSI systems. It addresses the need for precise impedance matching and signal termination in low-voltage differential environments. Its design simplifies board space by integrating multiple termination functions into a single package.

Replacement Considerations

As an obsolete part, direct replacements may require adapter boards or redesign. Verify pinout compatibility if substituting with similar LVD terminators. Check if newer generations from other manufacturers offer equivalent 27-termination capabilities in comparable packages.
