DS26C31MJ/883

The Texas Instruments DS26C31MJ/883 is a CMOS quad tri-state differential line driver housed in a 16-lead ceramic dual in-line package (CDIP), engineered to meet TIA/EIA-422-B balanced transmission requirements. Each of the four independent driver channels incorporates a separate tri-state enable control, allowing the outputs to assume a high-impedance state for multi-drop bus configurations. The CMOS design delivers low static power consumption while maintaining fast propagation delays and controlled output slew rates, supporting reliable data rates well into the tens of megabits per second. Output short-circuit current limiting safeguards the device during bus faults or contention, and the differential signaling format provides robust common-mode noise rejection over twisted-pair cabling.

This component is deployed in mission-critical systems such as military avionics data links, ground-vehicle vetronics, industrial automation networks, and high-rel instrumentation where signal integrity over long cable runs is essential. The /883 suffix denotes full MIL-STD-883 processing, ensuring operation over the -55°C to +125°C temperature range, a hermetically sealed ceramic package for extreme environments, and documented lot traceability. Procurement teams should recognize that DS26C31MJ/883 occupies a mature position in Texas Instruments’ military semiconductor portfolio; long lead times and eventual life-cycle transitions are typical for such high-reliability components, making forward planning and active part-lifecycle monitoring critical for sustained system support.
