PI3USB221AZWEX-13R

Analog Switches - Special Purpose Overview

The PI3USB221AZWEX-13R is a high-bandwidth USB switch IC designed for routing high-speed USB 2.0 signals in mobile and consumer electronics. It functions as a bidirectional 1:2 multiplexer/demultiplexer, supporting data rates up to 480 Mbps with a typical bandwidth of 1.6 GHz. The device operates at supply voltages between 2.3 V and 3.6 V, accepting I/O signals up to 5.5 V. Key electrical parameters include a maximum on-resistance (rON) of 6 Ω, a typical input capacitance of 4 pF, and a low-power standby current of 2 µA when disabled. It features over-voltage protection for D+/D- pins and meets ESD standards of 12 kV HBM on I/O pins.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix '-13R' against official Diodes Incorporated documentation to confirm pin 1 orientation and reel specifications. Confirm RoHS compliance status and lead-free 'Green' device definitions prior to procurement. Ensure the component matches the required UDFN package dimensions for your PCB layout.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring high-speed USB 2.0 signal switching with low insertion loss. Consider the 1.6 GHz bandwidth and 6 Ω rON for signal integrity. Verify that the 2.3 V to 3.6 V supply range aligns with the system power rails. Check if the 10-pin UDFN package fits the available board space.

Analog Switches - Special Purpose Part Context

This part belongs to the PI3USB221A family of high-speed USB switches from Diodes Incorporated. It is specifically engineered for portable electronics where space and power consumption are critical constraints. The device integrates multiple switches into a single compact package to simplify system design.

Analog Switches - Special Purpose Replacement Considerations

Check for other variants within the PI3USB221A series, such as PI3USB221AZUAEX or PI3USB221AZWEX, which may differ only in packaging or pin 1 orientation. Ensure any substitute maintains the same 1.6 GHz bandwidth and 6 Ω rON specifications.

Analog Switches - Special Purpose FAQ

What is the maximum voltage supported by the I/O pins?

The I/O pins accept signals up to 5.5 V, providing compatibility with various logic levels.

How does the device handle over-voltage conditions on data pins?

It offers over-voltage protection for D+/D- pins; if shorted to VBus, a signal less than 3.8 V typically transmits through the outputs.

What is the typical bandwidth of the switch?

The device has a typical bandwidth of 1.6 GHz, allowing high-speed signals to pass with minimal distortion.
