Enhanced Versions  
The IDT54/74FCT646/A/C consists of a bus transceiver  
with 3-state D-type flip-flops and control circuitry arranged for  
multiplexed transmission of data directly from the data bus or  
from the internal storage registers.  
The IDT54/74FCT646/A/C utilizes the enable control (G)  
and direction (DIR) pins to control the transceiver functions.  
SAB and SBA control pins are provided to select either real  
time or stored data transfer. The circuitry used for select  
control will eliminate 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 selects stored data.  
Data on the A or B data bus or both can be stored in the  
internal D flip flops by LOW-to-HIGH transitions at the  
appropriate clock pins (CPAB or CPBA) regardless of the  
select or enable control pins.  
• Military product compliant to MIL-STD-883, Class B
