DS2120E/T&R/C08

Overview

The DS2120E/T&R/C08 is a SCSI interface integrated circuit manufactured by Analog Devices under the Maxim Integrated brand. It belongs to the DS2120E series and falls under the Interface ICs subcategory. The component is designed for SCSI applications, providing necessary signal conditioning and protocol handling capabilities. The specific suffix /T&R/C08 indicates tape-and-reel packaging with RoHS compliance characteristics. This device serves as a specialized interface solution for connecting SCSI peripherals within computer systems.

Feature Summary

• Provides dedicated SCSI interface functionality
• Integrates signal buffering and protocol management
• Designed for reliable data transmission in SCSI environments

Applications

• SCSI peripheral connectivity
• Computer system interface design
• Data storage subsystem integration

Procurement Notes

Verify the exact manufacturer designation, as listings may reference either Maxim Integrated or Analog Devices due to corporate acquisition history. Confirm the RoHS status associated with the C08 suffix against current regulatory requirements. Check availability status carefully, as this part number is listed as obsolete or end-of-life in several distributor databases. Ensure the tape-and-reel packaging format matches your assembly equipment specifications before ordering.

Selection Notes

Select this component only if designing legacy SCSI systems requiring this specific interface chip. Verify compatibility with existing SCSI controllers and target devices. Consider that newer designs might benefit from more recent interface solutions. Confirm pinout and electrical characteristics match the original design intent. Review the datasheet for any specific termination or biasing requirements unique to this SCSI transceiver.

Part Context

This component is part of the broader Dallas Semiconductor/Maxim Integrated portfolio of interface chips. The DS2120 series was widely used in SCSI implementations during the era when Dallas Semiconductor operated independently. The company was later acquired by Maxim Integrated, which subsequently became part of Analog Devices. This historical context explains the varying manufacturer names found in documentation and supply chain records.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to the obsolete status of this specific SCSI interface IC, direct replacements may require redesigning the interface circuitry. Consult official Analog Devices or Maxim Integrated resources for potential modern alternatives compatible with SCSI standards.
