TC7USB221FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7USB221FT Dual SPDT USB Switch TC7USB221 is high-speed CMOS dual 1-2 multiplexer /demultiplexer. The low on resistance and the low capacitance of the switch allow connections to USB application. This device consists of dual individual two-inputs multiplexer/demultiplexer with common select input (S) and output enable ( OE ). The D+/D- inputs is connected to the D1+/D1- or D2+/D2- outputs determined by the combination both the select input (S) and output enable ( OE ). When the output enable ( OE ) input is held “H” level, the switches are open with regardless the state of select inputs and a high-impedance state exists between the switches. All inputs are equipped with protection circuits against static discharge. TC7USB221FT Weight TSSOP14-P-0044-0.65A: 0.06 g (typ.)

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).
