Description

The PI3USB224 is a 2:2 bidirectional multiplexer for high-speed differential and single ended signal applications (up to 720Mbps).

The PI3USB224 offers a high BW of 1.2GHz with channel RON of 13Ω (Typical). The PI3USB224 operates with a 3V to 3.6V power supply. It features ESD protection of up to ±8kV contact discharge and 2kV Human Body Model on its I/O pins.

The PI3USB224 provides fail-safe protection by isolating the I/O pins with high impedance when the power supply (V_CC) is not present.
