Ordering Information
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 VCC 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.
