PI3USB103ZLEX

Analog Switches - Special Purpose Overview

The PI3USB103ZLEX 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 3.6V and features a typical on-resistance (RON) of 3.0Ω at VDD = 3.0V, with a maximum of 5.0Ω. The device supports high-speed USB 2.0 signals up to 480 Mbps, offering a -3dB bandwidth of 1400MHz and near-zero propagation delay of 250ps. It provides low crosstalk (-33dB at 480Mbps) and off isolation (-30dB). The I/O pins include over-voltage protection capable of tolerating a short to Vbus. The component is housed in a 10-contact TQFN package measuring 1.3mm x 1.6mm x 0.75mm.

Analog Switches - Special Purpose Feature Summary

• Supports bidirectional signal routing for USB 2.0 High Speed and Full Speed standards
• Provides over-voltage protection allowing I/O pins to withstand shorts to Vbus
• Features low bit-to-bit skew and minimal propagation delay for signal integrity

Analog Switches - Special Purpose Applications

• Routing signals for USB 2.0 interfaces
• Hand-held devices requiring compact signal switching

Analog Switches - Special Purpose Procurement Notes

Verify the ordering suffix 'X' confirms tape and reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the specific lot date codes align with project requirements. Cross-reference the datasheet revision to validate electrical characteristics against current production batches.

Analog Switches - Special Purpose Selection Notes

Select this component for designs requiring a single differential channel switch with tight space constraints due to its small TQFN-10 footprint. Verify that the system power supply remains strictly within the 3.0V to 3.6V operating range. Consider the 3.0Ω typical on-resistance for signal attenuation calculations. Ensure logic inputs are driven rail-to-rail to minimize power consumption.
