TC7USB31WBG TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7USB31WBG Dual SPST USB Switch TC7USB31 is high-speed CMOS dual SPST USB Switch. The low ON- resistance and the low capacitance of the switch allow connections to USB application. The TC7USB31 requires the output enable ( OE ) input to be set high to place the output into the high impedance. All inputs are equipped with protection circuits against static discharge.

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
