1. Functional Description
• Dual SPDT USB Switch
2. 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.
3. Features
(1) Supply voltage: VCC = 2.3 to 3.6 V
(2) Switch terminal ON-capacitance: CI/O = 7 pF Switch ON (typ.) @VCC = 3.3 V
(3) ON-resistance: RON = 6.5 (typ.) @VCC = 3 V, VIS = 0 V
(4) RON flatness: RON(flat) = 1.6 (typ.)@VCC = 3 V
(5) Difference of ON-resistance between switches: RON = 0.5 (typ.)@VCC = 3 V
(6) ESD performance: Machine model ≥ ±200 V, Human body model ≥ ±2000 V
(7) Power-down protection provided on all inputs and outputs.
(8) Package: WCSP10B

Note:
Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even
destruction.
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).
