NCN9252
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 R_ON− 4 W (max) at 4.2 V V_CC, 5 W
(typ) at a 3.3 V V_CC. It also features low C_ON, < 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
R_ON and C_ON 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. An Evaluation Board specifically designed
for the NCN9252 is available and features USB connectors and test
points to allow straightforward testing of the device. Please see part
number NCN9252MUGEVB.
