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 real-time or stored data transfer. A low  
input level selects real-time data, and a high input  
level selects stored data. Figure 1 illustrates the  
four fundamental bus-management functions that  
can be performed with the ’HC652.

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) terminals regardless of the select- or  
output-control terminals. 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.
