description/ordering information  
The ’HCT646 devices consist of bus-transceiver circuits with 3-state outputs, 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 can be performed  
with the ’HCT646 devices.  
Output-enable (OE) and direction-control (DIR) inputs control the transceiver functions. In the transceiver  
mode, data present at the high-impedance port can be stored in either or both registers.
