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
through a shared USB connector port.
The NCN9252 features low RON− 4 W (max) at 4.2 V
, 5 W (typ) at a 3.3 V V

< 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 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.
