Apple MacBook Retina 12 Inch – A1534 Multiplexer Switch IC Chip – PI3DBS3224: 820-00145 / 820-00244 / U4450: QFN-32 PIN

The PI3DBS3224 is a 2:4 bidirectional multiplexer for highspeed differential and single ended signal applications.
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).
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.
