About Texas Instruments
Texas Instruments (TI) is a globally recognized leader in semiconductor innovation, with over 90 years of industry expertise. Their analog and embedded processing products set industry benchmarks for reliability across automotive, industrial, and communications markets.
TI components undergo rigorous testing for extreme temperature resilience, ESD protection, and long-term stability. Their design support resources and consistent manufacturing standards make TI ICs preferred solutions for mission-critical applications worldwide.

About Differential Line Drivers
Differential line drivers like the DS26LV31TMX transmit digital signals using complementary voltage pairs, significantly improving noise immunity compared to single-ended signaling. This balanced approach cancels electromagnetic interference during transmission, enabling reliable data transfer over extended cable runs.
Essential in industrial environments and high-speed communications, these ICs maintain signal integrity across temperature variations and electrically noisy conditions. Their low-voltage operation also reduces system power requirements while maintaining compatibility with legacy RS422/RS485 standards.

Packaging Options
Available in Tape & Reel (TR) for automated assembly or Cut Tape (CT) for prototyping needs. Specify packaging preference at checkout.

FAQs
Question: Is this IC compatible with 5V systems?
Answer: No, it requires a 3V-3.6V supply. Use voltage-level translators for 5V interfaces.

Question: What does “obsolete” status mean for availability?
Answer: Texas Instruments no longer manufactures this part, but PCX maintains limited stock. Contact us for long-term alternatives.

Question: Can I use this driver without external termination?
Answer: Termination resistors (typically 100Ω) are required at the receiver end for signal integrity in RS422/RS485 networks.

Question: Does it support half-duplex communication?
Answer: As a driver-only device (4/0 configuration), it requires companion receivers for bidirectional communication.

Question: What is the ESD protection rating?
Answer: It features ±15kV Human Body Model (HBM) protection on bus pins.
