Ics chips: 5PCS DM74LS74AN dual flip-flop preset output
Dual Positive-Edge-Triggered D Flip-Flops with Preset, Clear and Complementary Outputs
- 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.
