UC5604DPTR

Overview

The UC5604DPTR is a low-capacitance SCSI active terminator manufactured by Texas Instruments. It is designed for 9-line SCSI applications and operates within an input voltage range of 3.8 V to 5.25 V. The device draws a typical operating supply current of 220 µA. It is housed in a SOIC-Narrow-16 package, suitable for surface-mount installation. This component serves as a signal terminator for SCSI interfaces.

Feature Summary

• Provides active termination for 9-line SCSI bus architectures
• Features low capacitance design to maintain signal integrity at high speeds
• Operates with standard 5V logic supply voltages

Applications

• SCSI peripheral interface termination
• High-speed data transfer bus stabilization
• Computer storage system signal conditioning

Procurement Notes

Verify the specific manufacturer source and authenticity before procurement. Confirm that the component meets the required RoHS compliance standards for your project. Check for any end-of-life notices or availability constraints from the distributor. Ensure the package type matches your PCB footprint requirements exactly.

Selection Notes

Select this component when designing systems requiring active termination for 9-line SCSI connections. Consider the low capacitance feature for maintaining signal quality over longer traces. Evaluate the power consumption against system thermal limits. Ensure compatibility with the host controller's electrical specifications.

Part Context

This part belongs to the UCC561 series of SCSI interface integrated circuits. It functions specifically as a signal terminator rather than a general-purpose interface controller. The DPTR suffix indicates the tape-and-reel packaging format for automated assembly processes.
