What the ESD-protected USB transceiver rating means for your BOM
The MAX3454EEUD is an ESD-protected USB transceiver from Analog Devices, designed to handle the physical-layer signaling on a USB bus while shunting electrostatic discharge events that would otherwise reach the host controller or system-side logic. The ESD protection is integrated on the bus-facing pins, so the transceiver itself absorbs the transient — no external TVS diode needed between the connector and the IC, which saves board area and reduces per-port BOM cost.
RoHS compliance is marked as non-compliant, which matters for any BOM that must meet EU RoHS or similar restricted-substance regulations — the part contains lead (Pb) above the exemption threshold, so it is not suitable for a RoHS-mandated assembly without an exemption claim.
Package form and sourcing posture
Supplied in Bulk packaging — not tape-and-reel, so the quantity per reel or tube is not a constraint; the part is ordered as loose units or in the manufacturer's standard bulk pack.
