DS26LV31TMX

Overview

The DS26LV31TMX is a 3V enhanced CMOS 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 industrial temperature range of -40°C to +85°C. The device features a maximum power supply current of 100 μA at 3.3 V. Differential output voltage guarantees include a minimum of 2 V with a 100 Ω load and 3.2 V with a 3900 Ω load. Propagation delay ranges from 6 ns to 16 ns, with a maximum skew of 2.0 ns per channel. The component is available in a 16-pin SOIC package.

Feature Summary

• Compliant with TIA/EIA-422-B (RS-422) and ITU-T V.11 standards for interoperability with existing 5V RS-422 networks.
• Features low static power consumption suitable for battery-powered applications.
• Provides high ESD protection on cable I/O pins exceeding 7 kV via Human Body Model testing.
• Includes active-low or active-high control inputs for tri-state outputs.

Applications

• Industrial communication systems requiring RS-422 compliance
• Battery-operated electronic devices prioritizing low power consumption
• High-speed data transmission lines utilizing balanced twisted-pair cabling

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm RoHS compliance status and lead finish specifications. Confirm that the procurement source provides valid traceability records for the SOIC-16 package variant. Ensure the delivered components match the exact part number designation to avoid compatibility issues with existing circuit designs.

Selection Notes

Select this component when designing circuits that require strict adherence to RS-422 electrical specifications while operating at reduced 3.3 V logic levels. The low quiescent current makes it appropriate for energy-constrained environments. Verify that the system design accommodates the specified propagation delays and transition times for the intended data rates.

Part Context

This device belongs to the DS26LV31T family of quad differential line drivers. It serves as a pin-compatible alternative to older 5V RS-422 drivers, allowing for direct upgrades to lower voltage architectures without altering the physical footprint of the printed circuit board layout.
