MC74AC574, MC74ACT574  
Octal D Flip-Flop with  
3-State Outputs  
The MC74AC574/74ACT574 is a high–speed, low power octal  
flip–flop with a buffered common Clock (CP) and a buffered common  
Output Enable (OE). The information presented to the D inputs is  
stored in the flip–flops on the LOW–to–HIGH  
http://onsemi.com  
Clock (CP) transition.  
The MC74AC574/74ACT574 is functionally identical to the  
MC74AC374/74ACT374 except for the pinouts.

FUNCTIONAL DESCRIPTION

NC  
The MC74AC574/74ACT574 consists of eight edge-  
triggered flip–flops with individual D–type inputs and  
3–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) transition. With the Output Enable (OE) LOW,  
the contents of the eight flip–flops are available at the  
outputs. When 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.
