description/ordering information  
The CD54HC646 and CD74HCT646 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 these 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.  
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 active (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.  
When an output function is disabled, the input function still is enabled and can be used to store data. Only one  
of the two buses, A or B, can be driven at a time.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
