The MAX4906/MAX4906F/MAX4907/MAX4907F are analog switches that combine low capacitance and low resistance for high-performance switching applications. They are designed for USB 2.0 high-speed applications and can handle USB low-speed and full-speed signaling. These switches have a low threshold voltage and a high-level input voltage of +1.4V, making them suitable for low-voltage logic. They have low quiescent current and also feature a shutdown input to further reduce the quiescent current.
The MAX4906, MAX4906F, MAX4907 and MAX4907F are high‑/full‑speed USB 2.0 analog switches offered in compact 2 mm × 2 mm UDFN packages. They operate from a single +3.0 V to +3.6 V supply, provide low on‑resistance and low on‑capacitance, and include fault protection against shorts up to +5.5 V.
Typical applications include USB switching for cell phones, PDAs, digital cameras, notebooks, and Ethernet or bus switching. The devices feature a shutdown input that reduces quiescent current to under 2 µA, making them suitable for power‑sensitive designs.
