These devices consist of bus-transceiver circuits,  
D-type flip-flops, and control circuitry arranged for  
multiplexed transmission of data directly from the  
input bus or from the internal registers. Data on  
the A or B bus is clocked into the registers on the  
low-to-high transition of the appropriate clock  
(CLKAB or CLKBA) input. Figure 1 illustrates the  
four fundamental bus-management functions that  
are performed with the ’LVC646A.  
NC – No internal connection  
Output-enable (OE) and direction-control (DIR) inputs control the transceiver functions. In the transceiver  
mode, data present at the high-impedance port is stored in either register or in both.  
The select-control (SAB and SBA) inputs can multiplex stored and real-time (transparent mode) data. DIR  
determines which bus receives data when OE is low. In the isolation mode (OE high), A data is stored in one  
register and B data can be stored in the other register.  
When an output function is disabled, the input function is still enabled and can be used to store and transmit  
data. Only one of the two buses, A or B, can be driven at a time.
