description/ordering information  
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 can be performed with the ’BCT646 devices.  
Output-enable (OE) and direction-control (DIR) inputs are provided to control the transceiver functions. In the  
transceiver mode, data present at the high-impedance port can be stored in either register or in both.  
The select-control (SAB and SBA) inputs can multiplex stored and real-time (transparent mode) data. The  
direction control (DIR) determines which bus will receive data when OE is low. In the isolation mode (OE high),  
A data can be stored in one register and/or B data can be stored in the other register.
