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

Dual Positive-Edge-Triggered D Flip-Flops With Preset, Clear And Complementary Outputs

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.

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 Summary and Exercise are very important for perfect preparation.

Thank you for your suggestion regarding the switch.

EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something.

This DM contains two independent positive-edge-triggered D flip-flops with complementary outputs. The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock.

The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock. I see that as the resistance between the terminals goes up, the source voltage drops.

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.

What do I get?

There is a switch circled in red connected to CLR pin of the flip-flop. I circled the two parts I would like to better understand. Sign up using Facebook. You can see some Datasheet of IC sample questions with examples at the bottom of this page.

Do check out sm7474 sample questions of Datasheet of IC forthe answers and examples explain the meaning of chapter in the best manner.

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”. 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?

Recommended Operating Conditions Note 3: It is to introduce a potential value change to the input of the flip-flop. 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 and this in turn simulates the current dropping as per what you say is the purpose of the circuit.

The parametric values datasheeg in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.

On this basis, it seems to me like datashet functions as a “test” switch. Sign up using Email and Password. The sudden drop in current flow is taken as the signal to stop the voltage bias.
