WebThe 74LVC574A is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs. The device features a clock (CP) and output enable ( OE) inputs. The flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. WebHold time is the time after the latching clock edge in which an input signal should remain stable so that the output of flip-flop won't go into metastable state and can reach to its …
