Description
The FSA2357 is a Double-Pole, Triple Throw (DP3T)
multiplexer that routes three dual-channel sources of
data or audio under the control of three select pins. The
FSA2357 features very low quiescent current, which
allows mobile handset applications direct interface with
the baseband processor general-purpose I/Os. Typical
applications involve switching in portables and
consumer applications, such as cell phones, digital
cameras, and notebooks with hubs or controllers.
