The ’ABT640 bus transceivers are designed for  
asynchronous communication between data  
buses. These devices transmit inverted data from  
the A bus to the B bus or from the B bus to the  
A bus, depending on the level at the direction-  
control (DIR) input. The output-enable (OE) input  
can be used to disable the device so that the  
buses are effectively isolated.

To ensure the high-impedance state during power  
up or power down, OE should be tied to V  
CC  
through a pullup resistor; the minimum value of  
the resistor is determined by the current-sinking  
capability of the driver.  
The SN54ABT640 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74ABT640 is characterized for operation from –40°C to 85°C.
