General
The TC7USB221WBG 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 1D+/1D- or 2D+/2D- outputs determined by the
combination both the select input (S) and output enable (OE). When the output enable (OE) input is held high
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.
