DESCRIPTION
The TS3USB3031 is a double-pole, triple throw
(DP3T) multiplexer that includes a high speed Mobile
High-Definition Link (MHL) or Mobility Display Port
(MyDP) switch and dual USB 2.0 High-Speed
(480Mbps) switches in the same package. These
configurations allow the system designer to use a
common USB or Mico-USB connector for MHL/MyDP
signals and two sets of USB data. The MHL/MyDP
path supports the latest MHL Rev. 3.0 specification.
The TS3USB3031 has a V_CC range of 2.5V to 4.3V
and supports over-voltage tolerance (OVT) feature,
which allows the I/O pins to withstand over-voltage
conditions (up to 5.5V). The power-off protection
feature forces all I/O pins to be in high impedance
mode when power is not present, allowing full
isolation of the signals lines under such condition
without excessive leakage current. The select pins of
TS3USB3031 are compatible with 1.8V control
voltage, allowing them to be directly interfaced with
the General Purpose I/O (GPIO) from a mobile
processor.
The TS3USB3031 comes with a small 12-pin QFN
package with only 1.8mm x 1.8mm in size, which
makes it a perfect candidate to be used in mobile
applications.
