Octal D Flip-Flop  
General Description  
Features  
Y
Ideal buffer for microprocessor or memory  
The ’273 has eight edge-triggered D-type flip-flops with indi-  
vidual D inputs and Q outputs. The common buffered Clock  
(CP) and Master Reset (MR) input load and reset (clear) all  
flip-flops simultaneously.  
Y
Eight edge-triggered D flip-flops  
Y
Buffered common clock  
Y
Buffered, asynchronous master reset  
Y
The register is fully edge-triggered. The state of each D in-  
put, one setup time before the LOW-to-HIGH clock tran-  
sition, is transferred to the corresponding flip-flop’s Q out-  
put.  
See ’377 for clock enable version  
Y
See ’373 for transparent latch version  
Y
See ’374 for TRI-STATE version  
Y
Outputs source/sink 24 mA  
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.  
Y
’ACT has TTL-compatible inputs
