NLAS8252

DP3T Switch for

USB/UART/Data

Multiplexing

Brief Description

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 RON- 4 W (max) at 4.2 V VCC, 5 W

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

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

speed applications that require both low RON and CON for effective

signal transmission.

The NLAS8252 is capable of accepting control input signals down

to 1.4 V, over a range of VCC 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.

Features

• RON: 4 W Max @ VCC = 4.2 V

• CON: < 20 pF @ VCC = 3.3 V

• OVT Protection up to 5.25 V on Common Pins

• VCC Range: 1.65 V to 4.5 V

• 3 kV ESD Protection

• 1.7 x 2.0 x 0.5 mm UQFN12 Package

• This is a Pb-Free Device

Typical Applications

• USB/UART/Data Multiplexing

• Shared USB Connector

• Mobile Phones

• Portable Devices
