DS26C31TM selection and design context
DS26C31TM is cataloged as a RS-422 Line Driver in the DS26C31T family. Its recorded function is quad differential line driver for balanced RS-422 and RS-485 digital data transmission. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Drivers: 4. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Standards: TIA/EIA-422-B and RS-485 compatible. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Supply Voltage: 5 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Typical Propagation Delay: 6 ns. Confirm the value and its datasheet test conditions for the exact ordering suffix.
Application and qualification considerations
When evaluating this component, confirm the ratings that control system compatibility, including supply conditions, interface or signal limits, timing, thermal behavior and package constraints. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for DS26C31TM
The recorded package is 16-pin SOIC, the temperature range is -40°C to +85°C, and the lifecycle status is Production as of 2026-07-20. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.
