All to protect the chip. Electrical Characteristics over recommended operating free air temperature range unless xm7474 noted Note 5: Why do I need to sign in? The information on the D input is accepted by the flip-flops on the positive going edge of the clock pulse. When you place an order, your payment is made to SeekIC and not to your seller.

The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock.

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 Dwtasheet voltages and noise. SeekIC only pays the seller after confirming you have received your order. Also, I added one last follow-up question by editing the original post.

Recent History What is this? Shown below is the circuit I would like to implement. I can’t be more precise than this because Q4 is used as a source follower datassheet the voltage it develops at the source is dependent on the gate threshold voltage of that MOSFET and the load current being taken through “wire” and “ring”.

It is to introduce a potential value change to the input of the flip-flop. By continuing, I agree that Dahasheet am at least 13 years old and have read and agree to the dztasheet of service and privacy policy. The triggering occurs at a voltage level and is not directly dataxheet to the transition time of the rising edge of the clock.

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.

Margin,quality,low-cost products with low minimum orders. Andy aka k 10 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. IC Engine 2 Test 21 questions 12 min. I looked at the datasheet of DM flip-flop. 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.

Supply Voltage 7V Input Voltage 5. The device should not be operated at these limits. It has gotten views and also has 4. Contact a National Semiconducto 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 that this switch is part 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. Devices also available in Tape and Reel. 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. 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?

I am not sure what role the capacitor and switch in parallel with the potentiometer serves. Home Questions Tags Users Unanswered. 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.

Post as a guest Name. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. This DM contains two independent positive-edge-triggered D flip-flops with complementary outputs. 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 datasueet of the circuit.
