description  
These octal bus transceivers are designed for  
asynchronous communication between data  
buses. Thecontrolfunctionimplementationallows  
for maximum flexibility in timing.  
GND 10  
11 B8  
These devices allow data transmission from the A  
bus to the B bus or from the B bus to the A bus  
depending upon the logic levels at the output  
enable (OEAB and OEBA) inputs.  
SN54F621 . . . FK PACKAGE  
(TOP VIEW)  
The output-enable inputs can be used to disable  
the device so that the buses are effectively  
isolated. The dual-enable configuration gives the  
transceivers the capability of storing data by  
simultaneously enabling OEAB and OEBA. Each  
output reinforces its input in this configuration.  
When both OEAB and OEBA are enabled and all  
other data sources to the two sets of bus lines are  
at high impedance, both sets of bus lines (16 in all)  
will remain at their last states.
