OCTAL  
TRANSCEIVER/REGISTER  
WITH 3-STATE OUTPUTS  
(INVERTING)  
The MC74AC648/74ACT648 consist of registered bus transceiver circuits,  
with outputs, D-type flip-flops and control circuitry providing multiplexed transmission  
of data directly from the input bus or from the internal storage registers. Data on the  
A or B bus will be loaded into the respective registers on the LOW-to-HIGH transition  
of the appropriate clock pin (CAB or CBA). The four fundamental data handling  
functions available are illustrated in the following figures.
