Part Description: 54AC74 54ACT74 Dual D-Type Positive Edge-Triggered Flip-Flop

Part Details:

54AC74/54ACT74 July 2003 54AC74/54ACT74Dual D-Type Positive Edge-Triggered Flip-FlopGeneral Description Clear and Set are independent of clock Simultaneous LOW on C and S makes both Q and Q The AC/ ACT74 is a dual D-type flip-flop with Asynchronous D D Dual Clear and Set inputs and complementary (Q, Q) outputs. HIGH Information at the input is transferred to the outputs on thepositive edge of the clock pulse. Clock triggering occurs at a Features D-T voltage level of the clock pulse and is not directly related to n I reduced by 50% CC the transition time of the positive-going pulse. After the Clock n Output source/sink 24 mA Pulse input threshold voltage has been passed, the Data ype n ACT74 has TTL-compatible inputs input is locked out and information present will not be trans-ferred to the outputs until the next rising edge of the Clock n Standard Microcircuit Drawing (SMD) Pulse input. -- AC74: 5962-88520 Positive -- ACT74: 5962-87525 Asynchronous Inputs: n 54AC74 now qualified to 300Krad RHA designation, LOW input to S (Set) sets Q to HIGH level D refer to the SMD for more information LOW input to C (Clear) sets Q to LOW level D Edge-T Logic Symbols riggered Flip-Flop 10026601 10026602 IEEE/IEC Pin Names Description D , D Data Inputs 1 2 CP , CP Clock Pulse Inputs 1 2 C , C
