description  
The SN54ACT16651 and 74ACT16651 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.

Complementary 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. A low input  
level selects real-time data, and a high input level  
selects stored data. 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. Figure 1  
illustrates the four fundamental bus-management  
functions that can be performed with the  
SN54ACT16651 and 74ACT16651.
