ST2349A

4-bit dual supply level translator

without direction control pin

Preliminary Data

Features

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

totem pole driver

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

open drain pole driver

■ Bi-directional level translation without

direction control pin

■ Wide V voltage range of 1.65 to 3.6 V

QFN16L

(2.6 x 1.8 mm)

■ Wide V 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

Description

■ Low quiescent current (max 24 µA)

■ Able to be driven by totem pole and open drain

The ST2349A is a 4-bit dual supply level

translator which provides the level shifting

capability to allow data transfer in a multi-voltage

drivers

■ 5.5 V tolerant enable pin

system. Externally applied voltages, V and V ,

■ ESD performance on all pins: ±2 kV HBM

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.

■ Small package and footprint

QFN16 (2.6 x 1.8 mm) package

Applications

The ST2349A accepts a V from 1.65 to 3.6 V

and V from 1.80 to 5.5 V, making it ideal for

■ Low voltage system level translation

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.

■ Mobile phones and other mobile devices

■ I C level translation

■ UART level translation

The ST2349A supports power down mode when

is grounded/floating and the device is

disabled via the OE pin.
