These octal bus transceivers are designed for  
asynchronous two-way communication between  
data buses. The control-function implementation  
allows for maximum flexibility in timing.  
SN54HCT623 . . . FK PACKAGE  
(TOP VIEW)  
The ’HCT623 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.

The output-enable inputs disable the device so  
that the buses are effectively isolated. The  
dual-enable configuration gives the transceivers  
the capability to store data by simultaneously  
enabling OEAB and OEBA. Each output  
reinforces its input in this transceiver  
configuration. When both OEAB and OEBA are  
enabled and all other data sources to the two sets  
of bus lines are in the high-impedance state, both  
sets of bus lines (16 total) remain at their last  
states. The 8-bit codes appearing on the two sets  
of buses are identical.
