Bus transceiver in the LVC family
The Texas Instruments SN74LVC863PWLE is a bus transceiver from the LVC logic family, designed for bidirectional data flow between two independent buses. It handles the voltage translation and drive buffering typical of multi-drop backplane or memory-mapped I/O interfaces where signal integrity matters at moderate speeds.
RoHS non-compliant — BOM flag
This part is explicitly listed as RoHS non-compliant, which means it contains lead (Pb) above the exemption thresholds. For any assembly line that requires full RoHS conformance — most consumer, medical, and automotive builds after the EU RoHS directive — this part cannot be used without a waiver. It is a fit only for military, aerospace, or legacy repair applications where leaded solder is still permitted or exempted.
For a production pick-and-place line, Bulk requires manual tube feeding or a tray feeder — not a showstopper, but it adds a handling step versus reeled parts. For prototype builds or bench work, Bulk is actually more convenient since you can pull single units without depopulating a reel.
