DESCRIPTION/ORDERING INFORMATION  
This 8-bit (octal) noninverting bus transceiver  
contains two separate supply rails; B port has VCCB  
,
which is set at 3.3 V, and A port has VCCA, which is  
set at 5 V. This allows for translation from a 3.3-V to  
a 5-V environment, and vice versa.  
<br/>  
The SN74LVC4245A 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 device so the buses are  
effectively isolated. The control circuitry (DIR, OE) is powered by VCCA  
.
The SN74LVC4245A pinout allows the designer to switch to a normal all-3.3-V or all-5-V 20-pin '245 device  
without board re-layout. The designer uses the data paths for pins 2–11 and 14–23 of the SN74LVC4245A to  
align with the conventional '245 pinout.
