Active production — what it means for the BOM line
The 5486DMQB: RoHS non-compliant per the manufacturer's listing, which places it in the legacy lead-bearing build stream — a factor for BOMs that must meet RoHS 2/3 directives or for repair depots that require the original tin-lead finish for solder-joint reliability on military/aerospace assemblies.
XOR gate in the TTL/H/L family — function and fit
The 5486DMQB is a quad 2-input XOR gate from the TTL/H/L series, a standard logic family that operates from a 5 V supply rail and delivers the propagation delays and fan-out typical of bipolar TTL — a direct fit for legacy backplane, bus-arbitration, or parity-check circuits that were originally designed around the 5486 die. Supplied in Bulk packaging — loose tubes or trays, not tape-and-reel — so the handling and kitting process differs from a reel-fed pick-and-place line; the buyer should confirm the packing format matches the assembly floor's feeder setup before committing the BOM quantity.
