Octal Transceiver/Register with TRI-STATE Outputs

General Description  
Features  
Y
Independent registers for A and B buses  
The ’AC648 consists 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 (CPAB or  
CPBA). The four fundamental data handling functions avail-  
able are illustrated in Figures 1 thru 4 (See Page 2).
