onsemi Dual 3.3 V Analog Switch and Multiplexer IC NL3HS3124AMNTWG

The NL3HS3124AMNTWG is a 2-channel, 2-to-1 differential multiplexer/demultiplexer designed for high-speed serial interface applications such as USB 3.0 and PCI Express Generation 3. It supports bidirectional signal switching with a maximum data rate of 8 Gbps and features a high bandwidth of over 6.3 GHz at -3 dB. The device exhibits low insertion loss, measuring -0.5 dB at 100 MHz and -2.8 dB at 4.0 GHz, along with low return loss of -9.27 dB at 4 GHz and low crosstalk of -35 dB at the same frequency. The NL3HS3124AMNTWG operates within a voltage range of 3.0 V to 3.6 V and includes a shutdown pin for power-saving mode, with a standby current of less than 1 µA. It is housed in a compact 2.5 mm x 4.5 mm QFN20 package and is compliant with RoHS standards, being Pb-free, halogen-free, and BFR-free. The device also features robust ESD protection, with tolerances of 4000 V HBM, 300 V MM, and 2000 V CDM, making it suitable for demanding applications.
