DS26C31TM/NOPB

The Texas Instruments DS26C31TM/NOPB is a quad differential line driver designed to meet the TIA/EIA-422-B and ITU V.11 standards, featuring 3-state outputs that allow multiple drivers to share a balanced transmission bus. Housed in an SOIC-16 package, this device converts single-ended logic signals into complementary differential outputs with a wide common-mode voltage range and fast transition times, making it suitable for robust data transmission over twisted-pair cabling. The 3-state control inputs enable high-impedance output states, facilitating the implementation of multipoint bus architectures where multiple transmitting nodes must coexist without contention, and the device typically operates over an industrial temperature range of -40°C to +85°C.

Typical applications include industrial automation networks, PLC communication interfaces, motor drive encoder feedback lines, and avionics data buses where noise immunity and signal integrity over long cable runs are critical. It is also widely used in telecommunications infrastructure, test equipment, and high-reliability embedded systems that require dependable point-to-point or multidrop digital communication. From a procurement standpoint, the /NOPB suffix confirms lead-free, RoHS-compliant plating, aligning with modern environmental compliance mandates without sacrificing performance. The device remains in active production at Texas Instruments, avoiding end-of-life risks often associated with legacy interface components, and its industrial-grade specification makes it a versatile choice for non-aerospace applications that still demand extended temperature performance and long-term availability.
