The 74AC11646 consists 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-  
managementfunctionsthatcanbeperformedwith  
the 74AC11646.

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 may 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 may be stored in one register and/or B data may be stored in the other register.  
When an output function is disabled, the input function is still enabled and may be used to store and transmit  
data. Only one of the two buses, A or B, may be driven at a time.  
The 74AC11646 is characterized for operation from –40°C to 85°C.
