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.
