description  
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 logic level at the  
direction-control (DIR) input. The output enable  
(OE)inputcanbeusedtodisablethedevicesothe  
buses are effectively isolated.

(TOP VIEW)  
The SN74F245 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.
