High-/Full-Speed USB 2.0 Switches
General Description
The MAX4906/MAX4906F/MAX4907/MAX4907F analog
switches combine the low on-capacitance (CON) and
low on-resistance (RON) necessary for high-perfor-
mance 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/dou-
ble-throw (SPDT) switches, and the MAX4907/
www.DMaAtaXS4h9e0e7t4FUf.ecaotmure 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 VIH, 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 avail-
able in space-saving, 2mm x 2mm µDFN packages and
operate over a -40°C to +85°C temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
