DS2114Z

Overview

The DS2114Z is a SCSI Single-Ended (SE) terminator integrated circuit manufactured by Analog Devices Inc. It provides nine precise terminations for SCSI bus applications, ensuring signal integrity and impedance matching. The device operates within a supply voltage range of 4V to 5.5V and supports surface mount installation in a 16-SOIC package with a width of 3.90mm. Designed for commercial temperature environments, it functions reliably between 0°C and 70°C. This component is part of the DS2114 series, offering a compact solution for high-speed data transmission termination requirements in legacy and specialized storage systems.

Feature Summary

• Provides nine dedicated termination points for SCSI Single-Ended bus lines
• Ensures accurate impedance matching to maintain signal integrity
• Supports standard 5V logic levels with wide supply voltage tolerance
• Utilizes a compact 16-pin SOIC surface-mount package

Applications

• SCSI Single-Ended bus termination
• High-speed data storage interface circuits
• Peripheral connection termination networks

Procurement Notes

Verify the specific suffix and RoHS compliance status when ordering, as availability may vary by region. Confirm that the 16-SOIC footprint matches your PCB design constraints. Check current distribution channels for stock limitations, as this component may be subject to restricted supply or end-of-life notices from Analog Devices. Ensure compatibility with existing SCSI SE architecture before integration.

Selection Notes

Select the DS2114Z when designing SCSI Single-Ended interfaces requiring multiple precise terminations in a small form factor. It is suitable for applications needing reliable 120-ohm equivalent termination across nine lines. Consider thermal management within the 0°C to 70°C operating range. Evaluate power consumption against system budget, as the device draws current during operation. Compare against alternative terminators if space or pin count constraints differ.

Part Context

The DS2114Z belongs to the DS2114 family of SCSI interface components developed by Maxim Integrated, now part of Analog Devices. These devices are engineered to simplify the termination of SCSI buses, reducing board space and component count compared to discrete resistor networks. The series supports various SCSI standards, providing robust signal termination for industrial and commercial computing applications.
