Rev 1.2 DIO3202A USB2.0 High-Speed and Audio/USB/UART Switch with Negative Swing Capacity Features Descriptions Low Ron Audio/USB analog switch The DIO3202A is dual SPDT (Single Pole/Double Low USB Con: 5pF Throw) switch which combines low distortion Negative Signal Swing Capable audio/USB/UART and USB2.0 high-speed data Low Audio Distortion signal switching in the same low voltage device. USB Switch -3dB Bandwidth: 720MHz This architecture is designed to allow negative High Crosstalk and Off-isolation signal passing as low as 2V below ground. When Voltage Supply Operation: 2.7 to 5.5V a voltage is detected on V , DIO3202A will BUS Three Green Packaged: DQFN-10, immediately switch to USB mode. Due to ultra low QFN-10, MSOP-10 capacitance design, the audio channels (pin 3 and pin 4 input/outputs) are able to not only switch Applications audio signal but also high speed USB signal or Cell-Phone/PDA low voltage UART signal as well. MP3/MP4/PMP DIO3202A provides packages with Green or RoHS Portable Instrumentation Battery Powered Communications tiny 10L packages, and operates over a Computer Peripherals temperature range of -40C to 85C.
