DM74LS74A Dual Positive-Edge-Triggered D Flip-Flops with Preset, Clear and plementary Outputs August 1986 Revised March 2000 DM74LS74A Dual Positive-Edge-Triggered D Flip-Flops with Preset, Clear and plementary Outputs General Description This device contains two independent positive-edge-triggered D flip-flops with plementary outputs. The information on the D input is accepted by the flip-flops on the positive going edge of the clock pulse. The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock. The data on the D input may be changed while the clock is LOW or HIGH without affecting the outputs as long as the...
