PI3USB221ZEEX

Analog Switches - Special Purpose Overview

The PI3USB221ZEEX is a high-bandwidth USB 2.0 multiplexer/demultiplexer switch manufactured by Diodes Incorporated in a 10-contact TDFN package. It operates at supply voltages of 2.5 V and 3.3 V, with an operating range of 2.3 V to 3.6 V. The device supports I/O signals up to 5.5 V and features a maximum on-resistance (rON) of 6 Ω. Key electrical parameters include a typical bandwidth of 1.1 GHz, a maximum propagation delay of 0.25 ns, and a line enable time of 125 ns. Supply current is limited to 50 µA maximum, dropping to 2 µA in low-power mode when the output enable pin is disabled.

Analog Switches - Special Purpose Feature Summary

• Supports bidirectional switching for high-speed USB 2.0 signals with minimal attenuation and phase distortion.
• Features low power consumption with a dedicated low-power mode that reduces supply current significantly when disabled.
• Provides robust electrostatic discharge protection exceeding 8 kV contact on the USB signal path per IEC61000-4-2 standards.

Analog Switches - Special Purpose Applications

• Routing signals for USB 1.0, 1.1, and 2.0 interfaces
• Mobile Industry Processor Interface (MIPI) signal routing
• Handset and consumer applications such as cell phones, digital cameras, and notebooks

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized Diodes Incorporated channels or certified distributors. Confirm the specific ZE suffix corresponds to the 10-contact TDFN package variant. Check for recent Product Change Notifications regarding manufacturing site updates or material compliance changes. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring a compact solution for multiplexing differential USB data lines. The 1.1 GHz bandwidth ensures signal integrity for High-Speed USB 2.0 transfers. Consider the 5.5 V I/O tolerance if interfacing with mixed-voltage logic domains. The low on-resistance minimizes signal loss across the switch path.

Analog Switches - Special Purpose Part Context

This part belongs to the PI3USB221 family of high-speed USB switches. The ZE suffix specifically denotes the Thin Dual Flat No Lead (TDFN) package configuration. Other variants in the series include the XA suffix for the TLLGA package. The device is designed to replace discrete switching solutions in space-constrained mobile and consumer electronics.

Analog Switches - Special Purpose Replacement Considerations

Direct functional substitutes within the same package include the PI3USB221XAEX, which utilizes the TLLGA package instead of TDFN. Verify pinout compatibility and thermal characteristics before substituting between package types. Cross-reference datasheets to ensure identical bandwidth and voltage specifications match the original design requirements.

Analog Switches - Special Purpose FAQ

What is the maximum I/O voltage supported by the PI3USB221ZEEX?

The device accepts input/output signals up to 5.5 V, allowing compatibility with various logic levels while operating at lower supply voltages.

How does the device achieve low power consumption?

When the Output Enable (OE) pin is disabled (held high), the switch enters a low-power mode where the supply current drops to a maximum of 2 µA.

Is the PI3USB221ZEEX compliant with environmental directives?

Yes, the device is totally lead-free, fully RoHS compliant, and halogen/antimony free, meeting EU Directive 2002/95/EC and subsequent revisions.
