NCN9252 www.DataSheet4U.com High-Speed USB 2.0 (480 Mbps) DP3T Switch for USB/UART/Data Multiplexing Brief Description The NCN9252 is a DP3T switch for combined UART and USB 2.0 high−speed data 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 RON− 4 W (max) at 4.2 V VCC, 5 W (typ) at a 3.3 V VCC. It also features low CON, < 30 pF (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 CON for effective signal transmission. The NCN9252 is capable of accepting control input signals down to 1.4 V, 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 0.5 mm, UQFN package.
