NLSX4378

4-Bit 24 Mb/s Dual-Supply

Level Translator

The NLSX4378 is a 4−bit configurable dual−supply bidirectional

auto sensing translator that does not require a directional control pin.

The VCC I/O and VL I/O ports are designed to track two different

power supply rails, VCC and VL respectively. The VCC supply rail is

configurable from 1.65 V to 5.5 V while VL supply rail is

configurable to 1.65 V to 5.5 V. This allows voltage logic signals on

the VL side to be translated into lower, higher or equal value voltage

logic signals on the VCC side, and vice−versa.

The NLSX4378 translator has open−drain outputs with integrated

10 k

W pullup resistors on the I/O lines. The integrated pullup

resistors are used to pullup the I/O lines to either VL or VCC. The

NLSX4378 is an excellent match for open−drain applications such as

the I2C communication bus.

Features

• VL can be Less than, Greater than or Equal to VCC

• Wide VCC Operating Range: 1.65 V to 5.5 V

Wide VL Operating Range: 1.65 V to 5.5 V

• High−Speed with 24 Mb/s Guaranteed Date Rate

• Low Bit−to−Bit Skew

• Enable Input and I/O Lines have Overvoltage Tolerant (OVT) to

5.5 V

• Nonpreferential Powerup Sequencing

• Integrated 10 kW Pullup Resistors

• Small Space Saving Package − 2.02 x 1.54 mm mBump12

• This is a Pb−Free Device

Typical Applications

• I2C, SMBus, PMBus

• Low Voltage ASIC Level Translation

• Mobile Phones, PDAs, Cameras
