PI3USB102GZLEX

Analog Switches - Special Purpose Overview

The PI3USB102GZLEX is a single differential channel 2:1 multiplexer/demultiplexer USB 2.0 switch manufactured by Diodes Incorporated. It operates within a VDD range of 3.0V to 5.5V and supports High Speed (480 Mbps), Full Speed, and Low Speed USB 2.0 standards. The device features a typical on-resistance (RON) of 4.0Ω at 3.0V and a maximum of 5.0Ω. It provides a -3dB bandwidth of 1,000MHz with low bit-to-bit skew and near-zero propagation delay of 250ps. The Y+/Y- pins include over-voltage protection tolerating shorts to VBUS. It is housed in a 10-contact TQFN package (1.3mm x 1.6mm x 0.75mm).

Analog Switches - Special Purpose Feature Summary

• Supports bidirectional signal routing for USB 2.0 high-speed, full-speed, and low-speed data.
• Integrates over-voltage protection on Y+/Y- pins to clamp downstream devices during VBUS shorts.
• Features low channel capacitance and minimal propagation delay for high-fidelity signal transmission.
• Compatible with 1.8-V logic control signals for SEL and OE pins.

Analog Switches - Special Purpose Applications

• Routing signals for USB 2.0 interfaces.
• PC and notebook computer systems.
• Hand-held electronic devices.

Analog Switches - Special Purpose Procurement Notes

Verify the component against the official datasheet DS41285 Rev 1-2 to confirm electrical parameters and pinout compatibility. Ensure the ordering suffix ZLEX corresponds to the required tape and reel packaging format. Confirm RoHS 3 compliance and lead-free status requirements match the project specifications before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when a single-channel USB 2.0 switch with integrated over-voltage protection is required. The 10-TQFN package suits space-constrained designs. Verify that the 3.0V to 5.5V supply voltage range aligns with the system power architecture. Consider the 4.0Ω typical on-resistance and 1GHz bandwidth for signal integrity requirements in high-speed data paths.

Analog Switches - Special Purpose Part Context

The PI3USB102GZLEX belongs to the PI3USB102 series of USB 2.0 switches from Diodes Incorporated. This series focuses on providing compact solutions for signal multiplexing in portable electronics. The 'G' suffix indicates lead-free and green manufacturing compliance, while 'ZLEX' specifies the 10-contact TQFN package with tape and reel delivery.

Analog Switches - Special Purpose Replacement Considerations

The PI3USB102E is an alternative variant within the same family offering improved Ioff voltage range characteristics. Verify pin compatibility and specific leakage current requirements when substituting between these variants.
