PI3USB40AE

Analog Switches - Special Purpose Overview

The PI3USB40AE is a 3.3V, wide bandwidth, 8-channel multiplexer/demultiplexer switch with Hi-Z outputs and a single enable control. It routes physical layer signals for high-speed differential protocols like USB 2.0 (480 Mb/s). The device features bidirectional operation with minimal attenuation. Key electrical parameters include a typical on-resistance of 4Ω, low bit-to-bit skew of 200ps, and crosstalk of -27dB at 250MHz. It operates within a VCC range of +3.0V to +3.6V, consumes 20μA in standby, and offers ESD protection exceeding 2000V via the Human Body Model.

Analog Switches - Special Purpose Feature Summary
