The DIODES Advantage

The PI3USB3031, with its high bandwidth and low

propagation delays, supports the multiplexing of one

USB 2.0 input to three USB 2.0 signals.

The PI3USB3031 is a double-pole-triple-

throw multiplexer/demultiplexer supporting

differential dual- and single-ended channel

switching in high-performance PC and

smartphone applications.

With its 6.5GHz bandwidth and low 50ps

propagation delay, the PI3USB3031

ensures excellent signal integrity with full

eye diagram opening. It passes USB 2.0,

MHL (Mobile High-Definition Link), and

Mobility DisplayPort (MyDP) differential

signals. It also supports 2-channel, 1:3 mux

functions for single-ended signal

applications.

The PI3USB3031 boasts a low 28μA current

consumption, a wide supply voltage range

of 1.8V to 5.5V, and supports 1.8V logic on

control pins.

In power-down mode, it minimizes its

leakage current and disconnects the data

channels. The I/O pins can withstand

Overvoltage Tolerance (OVT) of up to 5.5V

without external components. This enables

the PI3USB3031 to provide a robust USB

2.0 port solution.

The PI3USB3031 is available in the tiny

W-QFN1818-12 and X2-QFN1616-12

packages.

6.5GHz Double-Pole-Triple-Throw Mux/DeMux with OVT for

USB 2.0 and MHL Switching in Portable Applications

PI3USB3031
