OVERVIEW

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 three terminals.

They are operated together to allow three data sources, such

as a USB or UART transceiver, to pass differential data

< 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 V CC 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.

through a shared USB connector port.

The NCN9252 features low RON ? 4 W (max) at 4.2 V

V CC , 5 W (typ) at a 3.3 V V CC . It also features low CON,
