UCC5646PM

Overview

The UCC5646PM is a signal terminator integrated circuit manufactured by Unitrode, designed for SCSI applications. It features 27 termination lines and provides a nominal impedance of 105 ohms. The component is housed in a 64-pin LQFP package with dimensions of 10x10 mm. This device serves as an interface solution for managing signal integrity in high-speed data transmission environments.

Feature Summary

• Provides dedicated termination for SCSI bus architectures
• Integrates multiple termination lines within a single package
• Designed to maintain signal integrity via controlled impedance

Applications

• SCSI interface circuits
• High-speed data bus termination
• Signal integrity management systems

Procurement Notes

Verify the manufacturer designation carefully, as Unitrode's semiconductor assets were acquired by Texas Instruments. Ensure the specific part number matches the required pinout and package style. Confirm RoHS compliance status through official documentation before procurement to meet regulatory standards.

Selection Notes

Select this component when a multi-line SCSI terminator is required for system design. The 105-ohm impedance specification must align with the target bus characteristics. Consider the 64-LQFP package constraints for PCB layout and thermal management during the selection process.

Part Context

This device belongs to the signal terminators category within the interface ICs family. It addresses the need for precise impedance matching in legacy and specialized communication protocols. The integration of multiple terminations reduces board space compared to discrete resistor networks.
