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 V voltage range of 1.65 to 3.6 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 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  
drivers  
5.5 V tolerant enable pin

ESD performance on all pins: 2 kV HBM  
on either side of the device. It utilizes  
Small package and footprint  
transmission gate-based design that allows bi-  
directional level translation without a control pin.  
QFN16 (2.6 x 1.8 mm) package  
The ST2349 accepts a V from 1.65 to 3.6 V and

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.
