The MAX4906/MAX4906F/MAX4907/MAX4907F analog switches combine the low on-capacitance (C_ON) and low on-resistance (R_ON) necessary for high-performance switching applications. These devices are designed for USB 2.0 high-speed applications at 480Mbps. These switches will also handle all the requirements for USB low- and full-speed signaling.

The MAX4906/MAX4906F feature two single-pole/double-throw (SPDT) switches, and the MAX4907/MAX4907F feature two single-pole/single-throw switches (SPST). The MAX4907/MAX4907F have a low 7Ω (max) on-resistance and 7pF (max) on-capacitance. These devices are fully specified to operate from a single +3.0V to +3.6V power supply and are protected against a +5.5V short to COM1 and COM2. This feature makes them fully compliant with the USB 2.0 specification of +5.5V fault protection. These devices feature a low threshold voltage and a +1.4V V_IH, permitting them to be used with low-voltage logic. The MAX4906/MAX4906F/MAX4907/MAX4907F operate at 300µA (max) quiescent current and feature a shutdown input to reduce the quiescent current to less than 2µA (max).

The MAX4906/MAX4906F/MAX4907/MAX4907F are available in space-saving, 2mm x 2mm µDFN packages and operate over a -40°C to +85°C temperature range.
