MC74AC273, MC74ACT273  
Octal D Flip−Flop  
The MC74AC273/74ACT273 has eight edge-triggered D−type  
flip−flops with individual D inputs and Q outputs. The common  
buffered Clock (CP) and Master Reset (MR) inputs load and reset  
(clear) all flip−flops simultaneously.  
The register is fully edge-triggered. The state of each D input, one  
setup time before the LOW−to−HIGH clock transition, is transferred  
to the corresponding flip−flop’s Q output.  
http://onsemi.com  
All outputs will be forced LOW independently of Clock or Data  
inputs by a LOW voltage level on the MR input. The device is useful  
for applications where the true output only is required and the Clock  
and Master Reset are common to all storage elements.
