DS26LS31MJ/883

The DS26LS31MJ/883 is a quad high-speed differential line driver from Texas Instruments, engineered to meet TIA/EIA-422-B and ITU-T V.11 standards for balanced digital data transmission. Housed in a rugged 16-pin ceramic dual-inline package (16-CDIP), this device converts single-ended TTL or CMOS logic signals into complementary differential outputs with tight skew and transition-time control. The four independent drivers feature active-high and active-low enable lines that place the outputs in a high-impedance state, facilitating multiplexed bus architectures. Characterized over the full military temperature range of -55°C to +125°C, it is fabricated using low-power Schottky technology, providing a typical differential output voltage swing that drives terminated twisted-pair cables with high noise immunity and minimal radiated emissions.

Typical deployments include high-reliability telemetry and command links in aerospace and defense platforms, such as flight control computers, radar signal distribution, and ground support equipment where data integrity must survive extreme environmental stress. Industrial applications cover motor drive interfaces, process automation nodes, and remote sensor networks requiring robust long-reach communication in electrically noisy settings. The “/883” suffix designates full compliance with MIL-STD-883 processing, encompassing screening, burn-in, and conformance testing; this eliminates all non-ceramic or commercial-grade compromises and makes the part suitable for programs requiring formal military or DSCC qualification. Procurement engineers should note that military-grade drivers of this class often carry extended lead times and should verify the manufacturer’s active-lifecycle status to avoid obsolescence risks in long-life platforms. Traceability documentation, lot segregation, and defined tin-lead finishes are standard with this part, supporting compliance-driven supply chains.
