I think I understand why the potentiometer is there. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.

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. When Q1 is off Q4’s gate is pulled to 12 volts via R1 and datasheeh means that at the source of Q4 is a voltage of around 8 volts to 10 volts. I think that this switch is part of the chip referred to as U24 and, as such U24 is probably an analogue switch controlled fatasheet another part of your circuit unseen in your question.

SeekIC only pays the seller after confirming you have received your order.


On this basis, it seems to me like it functions as a “test” switch. You can also find Datasheet of IC ppt and other slides as well. Please create an account or Sign in. What do I get?

If I want to implement the circuit, can I just have a switch connected to CLR without being concerned about the part of the circuit unseen? Already Have an Account? Basically, it’s a circuit designed to cut off voltage when electrochemical etching is done. Blackwidow 1 Neither high nor low of CLR fixes the output of Q. Margin,quality,low-cost products with low minimum orders. Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 5: The voltage at “ring” is also current dependent because it is connected to ground via a ohm potentiometer and this could be set to ohms and drop mV if 1 mA was flowing through “wire” and “ring”.

Thank you for your suggestion regarding the switch. 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. Contact a National Semiconducto This DM contains two independent positive-edge-triggered D flip-flops with complementary outputs.

Not more than one output should be shorted at a time. The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock.

EduRev is like a wikipedia just for education and the Datasheet of IC images and diagram are even better than Byjus! 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.

This is your solution of Datasheet of IC search giving you solved answers for the same. Freight and Payment Recommended logistics Recommended bank. 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. Q1’s gate is fed from a flip-flop hence it’s fairly clear that Q1 is used as an enable control for Q4. Home Questions Tags Users Unanswered.


Recent History What is this? 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. Devices also available in Tape and Reel. I am not sure what role the capacitor and switch in parallel with the potentiometer serves. The device should not be operated at these limits. 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. Datasheet of IC notes for is made by best teachers who have written some of the best books of.

The information on the D input is accepted by the flip-flops on the positive going edge of the clock pulse. 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.

Andy aka k 10 Shown below is the circuit I would like to implement.

Email Required, but never shown. 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 datasheeg 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.

I looked at the datasheet of DM flip-flop. We will also never share your payment details with your seller.
