Dual Positive-edge-triggered D Flip-flops With Preset, Clear And Complementary Outputs - National Semiconductor

This device 54LS74 DM54LS74A DM74LS74A contains two independent positive-edge-trig- gered D Flip-Flops with complementary outputs. The informa- tion on the D input is accepted by the Flip-Flops on the posi- tive 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 By National Semiconductor Corporation
