ST2349

4-bit dual supply level translator

without direction control pin

Features

■ 45 Mbps (max) data rate when driven by a

totem pole driver

■ 4 Mbps (max) data rate when driven by an

open drain pole driver

■ Bi-directional level translation without

direction control pin

■ Wide VL voltage range of 1.65 to 3.6 V

■ Wide VCC voltage range of 1.80 to 5.5 V

■ Power down mode feature – when either

supply is off, all I/Os are in high impedance

■ Low quiescent current (max 24 µA)

■ Able to be driven by totem pole and open drain

drivers

■ 5.5 V tolerant enable pin

■ ESD performance on all pins: ±2 kV HBM

■ Small package and footprint

QFN16 (2.6 x 1.8 mm) package

Applications

■ Low voltage system level translation

■ Mobile phones and other mobile devices

■ I2C level translation

■ UART level translation

Description

The ST2349 is a 4-bit dual supply level translator

which provides the level shifting capability to allow

data transfer in a multi-voltage system. Externally

applied voltages, VCC and VL, set the logic levels

on either side of the device. It utilizes

transmission gate-based design that allows bi-

directional level translation without a control pin.

The ST2349 accepts a VL from 1.65 to 3.6 V and

VCC from 1.80 to 5.5 V, making it ideal for data

transfer between low-voltage ASICs/PLD and

higher voltage systems. This device has a tri-state

output mode which can be used to disable all

I/Os.

The ST2349 supports power down mode when

VCC is grounded/floating and the device is

disabled via the OE pin.
