description  
These octal bus transceivers are designed for  
asynchronous two-way communication between  
data buses. These devices transmit 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  
GND  
(DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively  
isolated. The SN74ALS1640A features inverting logic, while the SN74ALS1645A features noninverting logic.  
The SN74ALS1640A and SN74ALS1645A are characterized for operation from 0°C to 70°C.
