description  
These devices consist of bus transceiver circuits,  
D-type flip-flops, and control circuitry arranged for  
multiplexed transmission of data directly from the  
data bus or from the internal storage registers.

Output-enable (OEAB and OEBA) inputs are  
provided to control the transceiver functions.  
Select-control (SAB and SBA) inputs are provided  
to select whether real-time or stored data is  
transferred. The circuitry used for select control  
eliminates the typical decoding glitch that occurs  
in a multiplexer during the transition between  
stored and real-time data. A low input selects  
real-time data, and a high input selects stored  
data. Figure 1 illustrates the four fundamental  
bus-managementfunctionsthatcanbeperformed  
with the ABT652.

NC – No internal connection  
Data on the A or B data bus, or both, can be stored in the internal D-type flip-flops by low-to-high transitions at  
the appropriate clock (CLKAB or CLKBA) inputs regardless of the select- or enable-control pins. When SAB and  
SBA are in the real-time transfer mode, it is possible to store data without using the internal D-type flip-flops by  
simultaneously enabling OEAB and OEBA. In this configuration, each output reinforces its input. When all other  
data sources to the two sets of bus lines are at high impedance, each set of bus lines remains at its last state.  
To ensure the high-impedance state during power up or power down, OEBA should be tied to V  
through a  
CC  
pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver  
(B to A). OEAB should be tied to GND through a pulldown resistor; the minimum value of the resistor is  
determined by the current-sourcing capability of the driver (A to B).  
The SN74ABT652 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count  
and functionality of standard small-outline packages in less than half the printed-circuit-board area.
