UCC5618DWPTR

Overview

The UCC5618DWPTR is an 18-line SCSI active terminator integrated circuit manufactured by Texas Instruments. It is designed to terminate SCSI bus lines, ensuring signal integrity in high-speed data transmission environments. The device operates within a specified voltage range and supports hot insertion capabilities to allow for system modifications without powering down the entire bus. It features low capacitance outputs to minimize signal reflection and distortion. The component is housed in a TSSOP-28 package, suitable for surface-mount applications requiring compact board space.

Feature Summary

• Provides active termination for up to 18 SCSI bus lines
• Supports hot insertion for safe bus reconfiguration
• Features low output capacitance to maintain signal quality
• Includes reverse disconnect protection

Applications

• SCSI bus termination in server systems
• Storage area network (SAN) equipment
• High-performance peripheral interconnects

Procurement Notes

Verify the specific suffix DWPTR against the manufacturer's official datasheet to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with existing SCSI controller logic levels before integration into the design.

Selection Notes

Select this component when designing systems requiring reliable termination for 18-line SCSI interfaces. Consider thermal management requirements associated with active termination circuits and ensure the PCB layout accommodates the TSSOP-28 footprint.

Part Context

This part belongs to the UCC5618 family of SCSI terminators from Texas Instruments. It serves as a critical interface component in legacy and specialized storage architectures where stable bus signaling is mandatory for data integrity.

Replacement Considerations

Potential substitutes include UC5608DWP for low capacitance applications or UCC5617 for reverse disconnect functionality. Verify pinout compatibility and electrical specifications before substitution.
