Description
The FSA2380 is a Double-Pole, Triple Throw (DP3T)
multiplexer that routes three dual-channel sources of
data or audio under the control of a single pair of select
pins. The FSA2380 has special circuitry on the 1A/2A
pins to allow a power-off feature. With the V
CC
supply
removed and voltage on the 1A/2A pins, there is
minimal leakage current into the 1A/2A data pins. The
FSA2380 also features very low quiescent current and a
power-off feature to extend battery life. The low
quiescent current feature 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.
Applications
Cell Phone, PDA, Digital Camera, and Notebook
LCD Monitor, TV, and Set-Top Box
