description  
The ’ABT16652 are 16-bit bus transceivers that  
consist of D-type flip-flops and control circuitry  
arranged for multiplexed transmission of data  
directly from the data bus or from the internal  
storage registers. These devices can be used as  
two 8-bit transceivers or one 16-bit transceiver.

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-management functions that can be  
performed with the ’ABT16652.  
2SAB 26  
2CLKAB 27  
2OEAB 28  
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 inputs. 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.
