Functional Description  
Truth Table  
The ’ACQ/’ACTQ374 consists of eight edge-triggered  
flip-flops with individual D-type inputs and TRI-STATE true  
outputs. The buffered clock and buffered Output Enable are  
common to all flip-flops. The eight flip-flops will store the  
state of their individual D inputs that meet the setup and hold  
time requirements on the LOW-to-HIGH Clock (CP) transi-  
tion. With the Output Enable (OE) LOW, the contents of the  
eight flip-flops are available at the outputs. When the OE is  
HIGH, the outputs go to the high impedance state. Operation  
of the OE input does not affect the state of the flip-flops.
