Maxim Integrated DS2119ME+T SCSI Terminator

The DS2119ME+T is a robust SCSI (Small Computer System Interface) terminator developed by Maxim Integrated, designed to provide reliable termination for SCSI bus lines. The device is engineered to meet the stringent requirements of the SCSI Parallel Interface (SPI) standards, ensuring compatibility with a wide range of SCSI devices and systems.

This terminator is part of the M series and comes in a surface-mountable 16-pin SOIC (Small Outline Integrated Circuit) package, making it suitable for compact system designs. The DS2119ME+T is specifically designed to terminate SCSI bus lines with the Ultra2 LVD (Low Voltage Differential) interface, which supports data transfer rates up to 80 MB/s. However, it also offers backward compatibility with SE (Single-Ended) applications, providing versatility for systems that may use different SCSI standards.

The DS2119ME+T features nine lines of termination with an integrated 2.7V bandgap reference that ensures precise termination voltages for the SCSI bus. This precise termination helps to reduce reflections and data errors on the bus, which is critical for maintaining the integrity of high-speed data transfers. Additionally, the device includes fail-safe biasing to maintain proper bus termination even when the bus is inactive or disconnected, further enhancing the reliability of the SCSI interface.

One of the key benefits of the DS2119ME+T is its ability to automatically switch between LVD and SE modes, providing seamless operation across different SCSI configurations. This auto-mode feature simplifies the design process for system integrators and reduces the need for manual configuration.

The DS2119ME+T is also characterized by its low power consumption, which is essential for maintaining energy efficiency in modern electronic systems. Its power-saving attributes, combined with its small form factor and high performance, make it an ideal choice for server systems, RAID arrays, storage devices, and other applications that require robust and reliable SCSI termination.

In summary, the Maxim Integrated DS2119ME+T SCSI terminator is an essential component for any system designer or integrator looking to ensure stable and fast data transfers within their SCSI-based systems. Its compatibility with various SCSI standards, automatic mode switching, and precise termination capabilities make it a versatile and reliable solution for a wide range of applications.
