Features
Description
ÎÎ2:4 Differential Multiplexer/Demultiplexer
The PI3DBS3224 is a 2:4 bidirectional multiplexer for highspeed differential and single ended signal applications (up to 720
Mbps). The PI3DBS3224 can be used in a 1:4 or dual 1:2 multiplexer/demultiplexer configuration. The PI3DBS3224 offers a
high BW of 1.2 GHz with channel RON of 13 Ω (Typ).

ÎÎPackage: 20-pin (TQFN) (3 x 3 mm, 0.4 mm pitch)
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.
