Andy aka k 10 Regarding the switch in red, if the circuit is currently driving current through datasheey and “ring” then closing the red switch will stop that current by turning off Q1 and this in turn simulates the current dropping as per what you say is the purpose of the circuit.

If I want to implement the circuit, can I dataeheet have a switch connected to CLR without being concerned about the part of the circuit unseen?

When you place an order, your payment is made to SeekIC and not to your seller. Also, I added one last follow-up question by editing the original post. At the time of measurement the clock is grounded.

I circled the two parts D,7474 would like to better understand.

This DM contains two independent positive-edge-triggered D flip-flops with complementary outputs. Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 5: Datasheet of IC Created by: I can’t be more precise than this because Q4 is used as a source follower and the voltage it develops at the source is dependent datashheet the gate threshold voltage of that MOSFET and the load current being taken through “wire” and “ring”.

Why do I need to sign in? It seems a little bit like trial and error and I think you’ll have to do this during installation. This is dj7474 solution of Datasheet of IC search giving you solved answers for the same.

You can see some Datasheet of IC sample questions with examples at the bottom of this page. I am not sure what role the capacitor and switch in parallel with the potentiometer serves. 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.

I think I understand why the potentiometer is there.

I might also consider putting 1 nF from the CLR input to ground as well. 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.

Month Sales Transactions. Neither high nor low of CLR fixes the output of Q. Faithfully describe 24 hours delivery 7 days Changing or Refunding. We will also never share your payment details with your seller. All to protect the chip. A low logic level on the preset or clear inputs will set or reset datasbeet outputs regardless of the logic levels of the other inputs.

Not more than one output should be shorted at a time.

Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or xm7474 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.

I think that this switch is dm74474 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. Thank you for your suggestion regarding the switch. I looked at the datasheet of DM flip-flop.

However, due to the nature of wiring to a regular switch I would want to insert maybe a 10 kohm resistor directly in series with pin 13 the CLR input to protect that pin from spurious ESD voltages and noise. 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.
