MAX4906, MAX4906F, MAX4907, MAX4907F
High-/Full-Speed USB 2.0 Switches
Designed for Portable Low-Power Applications that Require a Switching Function for One or More USB 2.0 Differential Pairs
|
Status
Active: In Production.
Description
The MAX4906/MAX4906F/MAX4907/MAX4907F analog
switches combine the low on-capacitance (CON) and
low on-resistance (RON) 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 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 available
in space-saving, 2mm x 2mm µDFN packages and
operate over a -40°C to +85°C temperature range.
