Andy aka k 10 You can also find Datasheet of IC ppt and other slides 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.

Continue with Google Continue with Facebook. 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. Freight and Payment Recommended logistics Recommended bank. EduRev is like a wikipedia just for education and the Datasheet of IC images and diagram are even better than Byjus!

Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 5: On this basis, it datsheet to me like it functions dtasheet a “test” switch. It is to introduce a potential value change to the input of the flip-flop. Please create an account or Sign in. 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 datasbeet its safety or effectiveness.

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.

I looked at the datasheet of DM flip-flop. Memory Cards, Modules WT This is somewhat of a separate question regarding the current being taken out of C1. Thank you for your response. We will also never share your payment details with your seller. 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?

D7474 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 datasheer 1 mA was flowing through “wire” and “ring”. Supply Voltage 7V Input Voltage 5.

This DM contains two independent positive-edge-triggered D flip-flops with complementary outputs. Share with a friend. Continue with Google or Continue with Facebook.

By continuing, I agree that I am at least 13 years old and have read and agree to the terms of service and privacy policy. Dahasheet up using Email and Password. I see that as the resistance between the terminals goes up, the source voltage drops. I might also consider putting 1 nF from the CLR input to ground as well.


I circled the two parts I would like to better understand. Not more than one output should be shorted at a time. Blackwidow 1 Already Have an Account? Email Required, but never shown. dm74744

Why do I need to sign in? The device should not be operated at these limits. Thank you for your suggestion.

Home Questions Tags Users Unanswered. 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. 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. Datasheet of IC notes for is made by best teachers who have written some of the best books of.

Recommended Operating Conditions Note 3: 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. All to protect the chip. You could use a regularl switch if you need what I think is the “test” daatsheet. Sign up or log in Sign up using Google.
