DS26LV31W-QML

Overview

The DS26LV31W-QML is a high-speed quad differential line driver manufactured by Texas Instruments. It operates within a supply voltage range of 3.0 V to 3.6 V and supports an operating temperature range from -55 °C to +125 °C. The device features four drivers with TRI-STATE outputs, providing a maximum quiescent power supply current of 125 µA. Differential output voltage specifications include a minimum of 4.0 V under no-load conditions and 2.0 V with a 100 Ω load. Propagation delay times are specified between 5.0 ns and 25.0 ns for both low-to-high and high-to-low transitions. The component utilizes a 16-pin Ceramic Flatpack (CFP) package.

Feature Summary

• Compatible with TIA/EIA-422-B and ITU-T V.11 standards
• Low static ICC of 125 µA max suitable for power-conscious applications
• TRI-STATE outputs with common enable/disable control
• Inputs compatible with LVTTL and LVCMOS logic levels

Applications

• Battery-powered communication systems
• Power-conscious industrial networks
• RS-422 balanced transmission lines

Procurement Notes

Verify the specific ordering suffix (e.g., W-QML.A or W-QML.B) against the required quality conformance inspection level per MIL-STD-883 Method 5005 Group A. Confirm that the CFP package dimensions align with the target footprint. Ensure procurement channels provide traceability documentation consistent with QML requirements.

Selection Notes

Select this component when a 3.3 V RS-422 driver with radiation-hardened or military-grade reliability is required. It serves as a pin-compatible alternative to standard 5V RS-422 drivers while maintaining interoperability with existing 5V networks. Verify input voltage compatibility with the system's logic family before integration.

Part Context

This part belongs to the DS26LV31QML series of enhanced CMOS quad differential line drivers. It is designed for digital data transmission over balanced lines in harsh environments. The device shares functional similarities with other RS-422 drivers but is distinguished by its specific QML qualification and low-voltage operation capabilities.

Replacement Considerations

The datasheet notes pin compatibility with the DS26C31. Verify electrical characteristics and voltage tolerances when substituting.
