Apple MacBook Retina 12 Inch - A1534 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. Printed Number: PI3DBS3224
