DS2117MX/T&R

Overview

The DS2117MX/T&R is a SCSI, LVD, SE, and ULT-3 compliant termination controller manufactured by Analog Devices Inc./Maxim Integrated. Designed for board-mount applications, this integrated circuit manages signal termination for high-speed data interfaces. It operates within a supply voltage range of 4V to 5.5V and supports an industrial temperature range from 0°C to 70°C. The device is housed in a compact 36-pin SSOP package with a width of 7.50mm. It features nine termination points to ensure signal integrity across SCSI bus architectures.

Feature Summary

• Supports SCSI Low Voltage Differential (LVD), Single-ended (SE), and Ultra SCSI-3 (ULT-3) interface standards
• Integrates active termination control logic for automated bus management
• Provides nine distinct termination output channels for comprehensive signal coverage

Applications

• SCSI host bus adapter termination circuits
• Peripheral device termination modules
• High-speed digital data transmission systems requiring LVD compliance

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm the specific suffix designation matches the required tape-and-reel packaging configuration. Ensure that the 36-SSOP footprint aligns with existing PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when designing SCSI interfaces requiring active termination control for LVD, SE, or ULT-3 modes. Verify that the 36-pin SSOP package dimensions fit the mechanical constraints of the target enclosure. Ensure the system power supply remains stable between 4V and 5.5V to maintain proper termination logic operation throughout the specified temperature range.

Part Context

This part belongs to the DS2117M family of SCSI termination controllers. It serves as a specialized interface solution for managing signal integrity in legacy and industrial storage systems. The MX variant specifically denotes the surface-mount SSOP package option, distinguishing it from other housing configurations within the same functional series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate pin-compatible alternatives only after verifying electrical parameter alignment and interface protocol support.
