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.
