DP3T Data Switch, USB 2.0 High Speed (480 Mbps), USB/UART/Data Multiplexing

The NCN9252 is a DP3T switch for combined UART and USB 2.0 high-speed applications.It allows portable systems to use a single external port to transmit and receive signals to and from three separate locations within the portable system. It is comprised of two switches each with a single common I/O that alternates between 3 terminals. They are operated together to allow three data sources such as a USB or UART transceiver to pass differential data through a shared USB connector port. The NCN9252 features low on-resistance 4ohms(max)with Vcc=4.2V and 5ohms (typ) at Vcc=3.3V. It also features low on-capacitance at 30pF(max) across the supply voltage range. This performance makes it ideal for both USB full-speed and high-speed applications that require both low Ron and low Con for effective signal transmission. The NCN9252 is capable of accepting control input signals down to 1.4V over a range of Vcc supply voltages with minimal leakage current. The NCN9252 is offered in a Pb-Free, 12 pin, 1.7 x 2.0 x 0.5mm, UQFN package.
