The PI3DBS3224 can be used in a :4 or dual :2 multiplexer/demultiplexer configuration. The PI3DBS3224 offers a high BW of.2 GHz with channel RON of 3 Ω (Typ). The PI3DBS3224 can also be used to fan out a differential or single ended signal pair to two ports simultaneously (fan-out configuration). The BW performance is lower in this configuration. The PI3DBS3224 operates with a 3 to 3.6V power supply. It features ESD protection of up to ±8-kV contact discharge and 2-kV Human Body Model on its I/O pins. The PI3DBS3224 provides fail-safe protection by isolating the I/O pins with high impedance when the power supply (VCC) is not present.
