What this part is and where it goes
The MAX3832UCB from Maxim Integrated is a 4-channel interconnect mux/demux — a signal-routing switch that lets a single input path be steered to one of four output paths, or vice versa. It is used in backplane routing, test-equipment signal switching, and any board-level interconnect where one signal source needs to be fanned out to multiple destinations or selected from multiple sources. The part is listed as active in its lifecycle and is RoHS non-compliant, a detail that matters for designs targeting RoHS-exempt or legacy-compliance builds.
RoHS non-compliance — what it means for the BOM
RoHS non-compliant means the MAX3832UCB uses lead (Pb) in its solder termination finish or internal construction, exempting it from the EU RoHS Directive's restriction on lead. This is common for high-reliability or military-grade interconnect parts where tin whisker risk from lead-free finishes is unacceptable. For a BOM line, this part fits only if your assembly process and end-market allow leaded solder — typically aerospace, defence, medical implant, or industrial equipment with a RoHS exemption.
Sourcing and procurement posture
The MAX3832UCB carries an active lifecycle status, meaning Maxim Integrated continues to manufacture and support it. The RoHS non-compliant status may narrow the pool of stocking distributors, but the active lifecycle means the supply chain is stable for ongoing production or repair spares.
