FSA3051TMX

The FSA3051 is a 6 Ω, bi-directional, low -power, two-port, high-speed, Single Pole / Double Throw (SPDT) analog switch. It features an extremely low on capacitance (C o N) of 7.7 pF and wide bandwidth of 1.0 GHz. The FSA3051 contains special circuitry on the switch I/O pins for applications where the VCC supply is powered-off (V c c = 0 V), which allows the device to withstand an over-voltage condition. This device is designed to minimize current consumption even when the control voltage applied to the select (S) pin is lower than the supply voltage (V C C). This feature is especially valuable to ultra-portable applications, such as cell phones, allowing for direct interface with the general-purpose I/Os of the baseband processor. Other applications include switching in portable cell phones, PDAs, digital cameras, printers, and notebook computers.
