Bus transceiver for high-reliability backplanes
The 54LCX245J-QML is a BUS TRANSCEIVER from the * series, designed for bidirectional data flow between two independent buses. This is a QML-qualified part, meaning it has passed the full QML certification flow for military and aerospace applications — not just a standard commercial or industrial grade. RoHS non-compliant means this part uses lead-bearing solder terminations; factor that into your assembly line's material declaration if you run lead-free processes.
QML qualification — what it means for the BOM
QML (Qualified Manufacturers List) certification is the highest screening level for defense and space-grade ICs. It covers the full manufacturing flow — wafer fab, assembly, test, and burn-in — under a DSCC-approved process. For a procurement manager, this means the 54LCX245J-QML carries traceability and lot-acceptance documentation that standard commercial transceivers lack. The active lifecycle is a green light for new designs: no imminent EOL, no forced redesign cycle. The trade-off is the RoHS non-compliant termination — if your contract manufacturer runs only lead-free profiles, you will need a waiver or a separate assembly line.
Bulk packaging — plan for manual or low-volume handling
That is typical for QML parts destined for hand-assembly, rework, or low-volume production runs. If your line expects reel-fed pick-and-place, factor in a tube-to-reel transfer step or order a different packaging variant. Bulk also means the parts arrive in anti-static tubes or trays — verify your incoming inspection process can handle loose devices without mixing.
