Overview

54LS74 DM54LS74A DM74LS74A Dual Positive-Edge-Triggered D Flip-Flops with Preset Clear and Complementary Outputs June 1989 54LS74 DM54LS74A 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 Features Y Alternate military aerospace device (54LS74) is available Contact a National Semiconductor Sales Office Distri...
