PI3USB20LE

Analog Switches - Special Purpose Overview

The PI3USB20LE is a 4-channel, 2:1 multiplexer/demultiplexer USB 2.0 switch manufactured by Diodes Incorporated. It operates within a supply voltage range of +3.0V to +3.6V and features a typical on-resistance (RON) of 4Ω with a maximum of 8Ω. The device provides a bandwidth exceeding 500 MHz and maintains low bit-to-bit skew of 200ps. Propagation delay is typically 250ps, while switching speed is 9ns. Input capacitance is 2.0pF typical, and off-isolation reaches -32dB. ESD protection exceeds 2000V via the Human Body Model. It is housed in a 16-pin TSSOP package.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and environmental compliance status. Ensure that any requested variants match the exact electrical specifications required for the target application. Cross-reference datasheet revision dates to confirm current manufacturing parameters before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring low propagation delay and high bandwidth for USB 2.0 data lines. The single enable input simplifies control logic compared to multi-enable alternatives. Verify that the operating temperature range meets system requirements and that the 16-pin TSSOP footprint aligns with the PCB layout constraints.
