SGM7222YMS10/TR

The SGM7222 is a high- speed, low- power double- pole/ double- throw (DPDT) analog switch that operates from a single 1.8V to 4.3V power supply. SGM7222 is designed for the switching of high- speed USB 2.0 signals in handset and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os. The SGM7222 has low bit- to- bit skew and high channel- to- channel noise isolation, and is compatible with various standards, such as high- speed USB 2.0 (480 Mbps). Each switch is bidirectional and offers little or no attenuation of the high- speed signals at the outputs. Its bandwidth is wide enough to pass high- speed USB 2.0 differential signals (480 Mb/s) with good signal integrity. The SGM7222 contains special circuitry on the D+ / D- pins which allows the device to withstand a V_BUS short to D+ or D- when the USB devices are either powered off or powered on. SGM7222 is available in Green TQFN- 1.8x1.4- 10L, MSOP- 10 and UTQFN- 1.8x1.4- 10L packages. It operates over an ambient temperature range of - 40°C to +85°C
