1 FSA2357 Low R ON 3:1 Analog Switch Features 10µA Maximum I CCT Current Over an Expanded Control Voltage Range: V IN=2.6V, V CC=4.5V On Capacitance (C ON): 70pF Typical 0.55Ω Typical On Resistance (R ON) -3db Bandwidth: > 120MHz Low Power Consumption (1µA maximum) Packaged in Pb-Free 14-Pin TSSOP and DQFN Priority Enable Control Circuitry Applications HDMI 5V Power Routing, LCD Monitor, TV, and Set-Top Box Cell Phone, PDA, Digital Camera, and Notebook Description July 2009 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.

3 Absolute Maximum Ratings 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. Symbol Parameter Min. Max.
