Brief Description

http://onsemi.com

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 features low R - 4 W (max) at 4.2 V V , 5 W

(typ) at a 3.3 V V . It also features low C , < 30 pF (max) across

the supply voltage range. This performance makes it ideal for USB full

speed applications that require both low R and C for effective

signal transmission.

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.

Detailed Description

switch, a signal can pass from the common pin to any of

three terminals. Whenever COM1 is closed to terminal 1S2,

COM2 will respectively be closed to terminal 2S2. The

select logic is controlled by two inputs, IN1 and IN2,

connecting the common pins to the terminals according to

the function table found on page 2. Since there are four

possible control states but only 3 possible terminals, the first

combination results in a open connection for all three

terminals.

The NLAS8252 is a DP3T switch designed for

applications where a single USB connector is used for

multiple data applications within a portable system. Two

differential signals from a USB connector can be routed to

3 different end locations. The first, channel 1, is optimized

for a full speed, USB 2.0 transceiver. The second and third,

channels 2 and 3, are optimized for UART or remote data

applications.

Control Inputs Select Logic

The NLAS8252 is made up of two, 3-throw switches

operating off of the same internal enable signal. For each
