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 ′BCT652.

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. Therefore,  
when all other data sources to the two sets of bus lines are at high impedance, each set of bus lines remain at  
its last state.  
The SN54BCT652 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN74BCT652 is characterized for operation from 0°C to 70°C.
