SN54/74LS623  
OCTAL BUS TRANSCEIVER  
WITH 3-STATE OUTPUT  
The SN54/74LS623 series is an octal bus transceiver designed for  
asynchronous two-way communication between data buses. Control function  
implementation allows maximum timing flexibility. Enable inputs may be used  
to disable the device so that buses are effectively isolated. Depending on the  
Logic Levels at the enable inputs, Data transmission is allowed from the A bus  
to the B bus or from the B bus to the A bus. The dual-enable configuration  
gives the LS623 the capability to store data by simultaneous enabling of GBA  
and GAB. Each output reinforces its input in this transceiver configuration.  
Thus, when both control inputs are enabled all other data sources to the two  
sets of bus lines (16 in all) will remain at their last states.
