MARKING  
DIAGRAM  
The NLAS8252 is a DP3T switch for combined UART and USB 2.0  
full 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 NLAS8252 is capable of accepting control input signals down  
to 1.4 V, over a range of V supply voltages with minimal leakage  
current. The NLAS8252 is offered in a lead-free, 12 pin, 1.7 x 2.0 x  
0.5 mm, UQFN package.
