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

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.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
