description  
These octal transceivers and line drivers 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 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.  
9 10 11 12 13  
Both the A-port and B-port outputs, which are designed to sink up to 12 mA, include equivalent 25-Ω series  
resistors to reduce overshoot and undershoot.  
When V  
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 2.1 V, OE should be tied to V  
the minimum value of the resistor is determined by the current-sinking capability of the driver.  
through a pullup resistor;

The SN54ABTR2245 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74ABTR2245 is characterized for operation from –40°C to 85°C.
