MC54/74F379  
QUAD PARALLEL REGISTER  
The MC54/74F379 is a 4-bit register with a buffered common enable. This  
deviceissimilartotheF175butfeaturesthecommonEnableratherthancom-  
mon Master Reset.  
The F379 consists of four edge-triggered D-type flip-flops with individual  
D inputs and Q and Q outputs. The Clock (CP) and Enable (E) inputs are com-  
mon to all flip-flops. When E is HIGH, the register will retain the present data  
independentof the CP input. The Dn and E inputs can change when the clock  
is in either state, provided that the recommended setup and hold times are  
observed. This circuit is designed to prevent false clocking by transitions on  
the E input.
