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. 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 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 octal bus  
transceivers and registers

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) 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.  
The -1 versions of the SN74ALS651A and SN74ALS652A are identical to the standard versions except that the  
recommended maximum I  
SN54ALS652, SN54ALS653, SN74ALS653, and SN74ALS654.  
for the -1 versions is increased to 48 mA. There are no -1 versions of the  
OL
