High-/Full-Speed USB 2.0 Switches

General Description

Features

♦ Fully Specified for a Single +3.0V to +3.6V

The MAX4906/MAX4906F/MAX4907/MAX4907F analog

switches combine the low on-capacitance (C ) and

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/

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

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).
