Do check out the datasheet questions of Datasheet of IC forthe answers and examples explain the meaning of chapter in the best manner. 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.

Datasheet of IC 7474

A critical component in any component of a life support device or system whose failure to perform can be rea- sonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.

I might also consider putting 1 nF from the CLR input to ground as well. Datasheet of IC Created by: When Q1 is off Q4’s gate is pulled to 12 volts via R1 and this means that at the source of Q4 is a voltage of around 8 volts to 10 volts.

I looked at the datasheet of DM flip-flop.

It’s difficult to answer because there are no well-defined on or off states for Q3 – it acts like a unity gain voltage buffer and when the resistance between the terminals starts to increase, current through the potentiometer drops and the voltage across it drops hence the source voltage drops and this causes a current to be taken out of C1 and hopefully produces enough of a positive rise in voltage on the output of the op-amp to clock the flip-flop output and turn off the process.

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.

I think that this switch is part of the chip referred to as U24 and, as such U24 is probably an analogue switch controlled by another part of your circuit unseen in your question.

Neither high nor low of CLR fixes the output of Q. The information on the D input is accepted by the flip-flops on the positive going edge dm747 the clock pulse.

So I guess I have to datashet my potentiometer value such that the gate voltage of Q3 gets some voltage above the threshold when in the process dataxheet etching and gets zero when the etching is over since when etching is done, the resistance value will shoot up. You can see some Datasheet of IC sample questions datsheet examples at the bottom of this page.

Q1’s gate is fed from a flip-flop hence it’s fairly clear that Q1 is used as an enable control for Q4. 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.

The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock. Contact a National Semiconducto All to protect the chip. Share with a friend. What do I d7m474

Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, and c whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be rea- sonably expected to result in a significant injury to the user.

Not more than one output should be shorted at a time. On this basis, it seems to me like it functions as a “test” switch.
