description  
The ’ABT863 devices are 9-bit transceivers  
designed for asynchronous communication  
between data buses. The control-function  
implementation allows for maximum flexibility in  
timing.

These devices allow noninverted data  
transmission from the A bus to the B bus or from  
the B bus to the A bus, depending on the logic  
levels at the output-enable (OEAB and OEBA)  
inputs.

The outputs are in the high-impedance state  
during power up and power down. The outputs  
remain in the high-impedance state while the  
device is powered down.  
NC – No internal connection  
When V  
is between 0 and 2.1 V, the device is  
CC  
in the high-impedance state during power up or  
power down. However, to ensure the  
high-impedance state above 2.1 V, OE should be  
tied to V through a pullup resistor; the minimum  
CC  
value of the resistor is determined by the  
current-sinking capability of the driver.  
The SN54ABT863 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74ABT863 is characterized for operation from –40°C to 85°C.
