GENERAL DESCRIPTION

The RS2228 is a high-speed, low-power doublepole/double-throw (DPDT) analog switch with single Enable. It is designed to operate from 1.8 V to 5.5 V. 

The RS2228 has a bus-switch enable pin, OE̅̅̅̅, that can place the signal paths in high impedance. This allows the user to isolate the bus when it is not in use and consume less current. 

The RS2228 is a high-bandwidth switch specially designed for the switching of high-speed USB2.0 signals in handset and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os. 

The RS2228 is available QFN1.4×1.8-10L package. It operates over an ambient temperature range of -40°C to +85°C.
