Overview
DM74LS74A Dual Positive-Edge-Triggered D Flip-Flops with Preset, Clear and Complementary Outputs August 1986 Revised March 2000 DM74LS74A Dual Positive-Edge-Triggered D Flip-Flops with Preset, Clear and Complementary Outputs General Description This device contains two independent positive-edge-triggered D flip-flops with complementary 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 data setup and hold times are not violated.
A low logic level on the preset or clear inputs will set or reset the outputs regardless of the logic levels of the other inputs.
