Description
The FSA2367 is a triple Single-Pole Double-Throw
(SPDT) switch that multiplexes three sources of data or
audio under independent control pins. The FSA2367
has special circuitry on the 1A, 2A, 3A pins that allows a
power-off feature. With the V_CC supply removed and a
voltage on the 1A/2A/3A pins, there is minimal leakage
current into the 1A/2A/3A data pins. In addition, the
FSA2367 also features very low quiescent current to
extend battery life. The low quiescent current 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.
