These octal bus transceivers are designed for  
asynchronous two-way communication between  
data buses. The control-function implementation  
allows for maximum flexibility in timing.

SN54HC623 . . . FK PACKAGE  
(TOP VIEW)  
The ’HC623 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.

OEAB and OEBA 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  
thetwosetsofbuslinesareinthehigh-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.
