UCC5618N

Overview

The UCC5618N is an 18-line SCSI active terminator manufactured by Texas Instruments. Designed for high-speed data transmission, it provides termination for SCSI bus lines to prevent signal reflections. The component operates within a specified voltage range and supports hot-insertion capabilities, allowing connections without system power-down. It integrates internal circuitry to manage line termination efficiently in parallel computer systems.

Feature Summary

• Supports 18-line SCSI bus termination
• Enables hot-insertion functionality
• Provides reverse disconnect protection

Applications

• Parallel SCSI bus termination
• High-speed data transmission systems
• Computer peripheral interconnects

Procurement Notes

Verify the manufacturer marking and date code against official Texas Instruments documentation. Confirm the package type matches the required board layout specifications. Ensure the component lot is free from counterfeit indicators by checking serial numbers on the manufacturer's verification portal before integration into production.

Selection Notes

Select this component when designing systems requiring standardized 18-line SCSI termination. Compare thermal performance and pin compatibility with existing designs. Verify that the operating temperature range meets the environmental requirements of the target application environment.

Part Context

This part belongs to the UCC5618 family of SCSI terminators. It serves as a critical interface component in legacy parallel storage architectures. The N suffix typically denotes a specific package variant or qualification level defined by the manufacturer for industrial or commercial use cases.

Replacement Considerations

The UCC5618QPTR is a documented equivalent alternative within the same product family. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part meets the same thermal and mechanical constraints as the original design.
