The ’ABT861 are 10-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.

When V  
is between 0 and 2.1 V, the device is

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 SN54ABT861 is characterized for operation  
over the full military temperature range of –55°C  
to 125°C. The SN74ABT861 is characterized for  
operation from –40°C to 85°C.
