(TOP VIEW)  
These octal bus transceivers are designed for  
asynchronous communication between data  
buses. The devices transmit data from the A bus  
to the B bus or from the B bus to the A bus  
depending upon the 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 SN74BCT245 is available in TI’s shrink  
small-outline package (DB), which provides the  
same I/O pin count and functionality of standard  
small-outline packages in less than half the  
printed-circuit-board area.

The SN54BCT245 is characterized for operation  
over the full military temperature range of 55°C  
to 125°C. The SN74BCT245 is characterized for  
operation from 0°C to 70°C.
