Product details

Package and mounting

Rated from -40°C to 85°C, this mux handles outdoor telecom cabinets, unheated factory floors, and engine-bay-adjacent enclosures — not just air-conditioned racks. The 32-TQFN (5x5 mm) with exposed pad is a hand-solderable package if you have hot air and a steady hand; the pad underneath needs a thermal via or a solid ground pour to sink heat. No through-hole version exists, so plan for a stencil or a rework station if you're prototyping.

Lifecycle and sourcing posture

The MAX4999ETJ+T carries an Active lifecycle status and is ROHS3 compliant.

Frequently asked questions

Does MAX4999ETJ+T support USB 2.0 high-speed switching?

Yes, the part is explicitly listed with USB 2.0 features and a 1.2 GHz -3dB bandwidth, which is more than sufficient to pass 480 Mbps USB 2.0 high-speed signals with good signal integrity.
