description/ordering information  
This 16-bit noninverting bus transceiver uses two  
separate configurable power-supply rails. The  
A port is designed to track V  
. V  
accepts  
CCA CCA  
any supply voltage from 1.65 V to 5.5 V. The B port  
is designed to track V . V accepts any  
CCB

CCA  
supply voltage from 1.65 V to 5.5 V. This allows for  
universal low-voltage bidirectional translation  
between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V  
voltage nodes.

The  
SN74LVC16T245  
is  
designed  
for  
asynchronous communication between data  
buses. The device transmits data from the A bus  
to the B bus or from the B bus to the A bus,  
depending on the logic level at the  
direction-control (DIR) input. The output-enable  
(OE) input can be used to disable the outputs so  
the buses are effectively isolated.  
The SN74LVC16T245 is designed so that the  
control pins (1DIR, 2DIR, 1OE, and 2OE) are  
supplied by V  
.
