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.

Features

• ESD performance: Machine model ≥ ± 200 V

Human body model

≥ ± 2000 V

• Power-down protection for inputs ( OE and S, I/O)

• Package: TSSOP14
