OCTAL D-TYPE  
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  
Clock (CP) transition.  
The MC74AC574/74ACT574 is functionally identical to the MC74AC374/  
74ACT374 except for the pinouts.  
Inputs and Outputs on Opposite Sides of Package  
Allowing Easy Interface with Microprocessors  
Useful as Input or Output Port for Microprocessors  
Functionally Identical to MC74AC374/74ACT374  
3-State Outputs for Bus-Oriented Applications  
Outputs Source/Sink 24 mA
