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.","metaTitle":"MAX4999ETJ+T USB 2.0 8:1 Multiplexer, 1.2 GHz, 32-TQFN","metaDescription":"MAX4999ETJ+T 8:1 analog multiplexer with 1.2 GHz bandwidth, 12 Ohm on-resistance, USB 2.0 support.
