TC7USB221FT
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.)
