The NCN9252MUTAG is a Double-pole triple-throw (DP3T) Analog 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 an USB or UART transceiver, to pass differential data through a shared USB connector port. The NCN9252 features low RON- 4 (max) at 4.2V VCC, 5 (typical) at a 3.3V VCC. It also features low CON, < 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 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.
