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  
L
QFN16L  
(2.6 x 1.8 mm)  
Wide V voltage range of 1.80 to 5.5 V  
CC  
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 ,  
CC  
L
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  
L
and V from 1.80 to 5.5 V, making it ideal for  
CC  
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  
V
is grounded/floating and the device is
