It has gotten views and also has 4. 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 satasheet 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.
Already Have an Account? I think I understand why the potentiometer is there. The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock.

The device should not be operated at these limits. The information on the D input is accepted by the flip-flops on the positive going edge of the clock pulse. Regarding the switch in red, if the circuit is currently driving current through “wire” and “ring” then closing the red switch will stop that current by turning off Q1 datasheef this in turn simulates the current dropping as per what you say is the purpose of the circuit.
Recent History What is this? All to protect the chip. So without knowing the current through “wire” and “ring” and the value if the potentiometer it’s impossible to state what the voltage across them is. I circled the two parts I would like to better understand. Continue with Google Continue with Facebook.
Do check out the sample questions of Datasheet of IC forthe answers dk7474 examples explain the meaning of chapter in the best manner. Home Questions Tags Users Unanswered. So I guess I have to choose my potentiometer value such that the gate voltage of Q3 gets some voltage above the threshold when in the process of etching and gets zero when the etching is over since when etching is done, the resistance dm74774 will shoot up.
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. Margin,quality,low-cost products with low minimum orders.
Not more than one output should be shorted at a time. EduRev is like a wikipedia just for education and the Datasheet of IC images and diagram are even better than Byjus!
I haven’t processed the first half of your answer but regarding the switch in red, the circuit schematic I have above is all of what I’m given.
I might also consider putting 1 nF from the CLR input to ground as well. Freight and Payment Recommended logistics Recommended bank. You can also find Datasheet of IC ppt and other slides as well. Share with a friend.
Thank you for your suggestion.

Post as a guest Name. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. It seems a little bit like trial and error and I think you’ll have to do this during installation. You could use a regularl switch if you need what I think is the “test” feature.
On this basis, it seems to me like it functions as a “test” switch. We will also never share your payment details with your seller.
