SN74LS74A Dual D-Type Positive Edge-Triggered Flip-Flop The SN74LS74A dual edge-triggered flip-flop utilizes Schottky TTL circuitry to produce high speed D-type flip-flops. Each flip-flop has individual clear and set inputs, and also complementary Q and Q outputs. Information at input D is transferred to the Q output on the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level of the clock pulse and is not directly related to the transition time of the positive-going pulse. When the clock input is at either the HIGH or the LOW level, the D input signal has no effect. http://onsemi.com LOW POWER SCHOTTKY MODE SELECT – TRUTH TABLE INPUTS OPERATING MODE SD Set Reset (Clear) *Undetermined Load “1” (Set) Load “0” (Reset) * L H L H H SD H L L H H D X X X [ ... ]
