The ′BCT544 octal registered transceiver  
contains two sets of D-type latches for temporary  
storage of data flowing in either direction.  
Separate latch-enable (LEAB or LEBA) and  
output-enable (OEAB or OEBA) inputs are  
provided for each register to permit independent  
control in either direction of data flow.  
SN54BCT544 . . . FK PACKAGE  
(TOP VIEW)  
The A-to-B enable (CEAB) input must be low in  
order to enter data from A or to output data from  
B. If CEAB is low and LEAB is low, the A-to-B  
latches are transparent; a subsequent low-to-high  
transitionofLEABputstheAlatchesinthestorage  
mode. With CEAB and OEAB both low, the 3-state  
B outputs are active and reflect the inverted data  
present at the output of the A latches. Data flow  
from B to A is similar, but requires using the CEBA,  
LEBA, and OEBA inputs.
