<strong>74F74</strong><strong>Dual</strong> D-<strong>Type</strong> <strong>Positive</strong> <strong>Edge</strong>-<strong>Triggered</strong> <strong>Flip</strong>-<strong>Flop</strong>General DescriptionThe F74 is a dual D-type flip-flop with Direct Clear and Setinputs and complementary (Q, Q) outputs. Information atthe input is transferred to the outputs on the positive edgeof the clock pulse. Clock triggering occurs at a voltage levelof the clock pulse and is not directly related to the transitiontime of the positive-going pulse. After the Clock Pulse inputthreshold voltage has been passed, the Data input islocked out and information present will not be transferred toOrdering Code:April 1988Revised July 1999the outputs until the next rising edge of the Clock Pulseinput.Asynchronous Inputs:LOW input to S D sets Q to HIGH levelLOW input to C D sets Q to LOW levelClear and Set are independent of clockSimultaneous LOW on C D and S Dmakes both Q and Q HIGHOrder Number Package Number Package Description<strong>74F74</strong>SC M14A 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150 Narrow<strong>74F74</strong>SJ M14D 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide<strong>74F74</strong>PC N14A 14-Lead Plastic <strong>Dual</strong>-In-Line Package (PDIP), JEDEC MS-001, 0.300 WideDevices also available in Tape and Reel.
