Can anyone please help me sort out the problem?. The time now is What is the function of TR1 in this circuit 3. Being not a machine, I always do silly mistakes or miss important things.

Problem with 74LS latching! Turn on power triac – proposed circuit analysis 0. Relay latching in AT89C51 based circuit This means that while your Enable is active and in your circuit it is always active – pin 11 high then the data presented to an input will always immediately get reflected to the output.

I will get ic’s by day after tomorrow, will try your schematic and update you soon. Need to either set LE low to latch the input or choose different latch.

The initial state of the LED is off U3 output is low.

This IC operates with maximum of 5 V and widely used in many kinds ddata electronic appliances. Equating complex number interms of the other 6. Each momentary switch would latch a solenoid valve and when activated switch off the others valvesa bit like a manual washing machine.

Here is an example http: PNP transistor not working 2. Latest posts by Frank Donald see all.

If you have CD, the remaining 2 gates can be used to combine the 2 switches in one. How reliable is it? Help with Latch IC 74LS based latching ciruit I actually made a similar sheeet back in the 80’s when experimemting with programmable logic the good old days! Hierarchical block is unconnected 3.

Last edited by sharikbaig; 27th August at But when the Latch Enable Pin was pulled low, the data will be latched so that the data appears instantaneously providing a Latching action. Enable gates pin 11 high 2.

When the OE pin is low input data will appear in the output. Our main server could be out of service anytime.

Frank Donald October 27, 2 Comments. Vata beauty of this simple circuit is it actually debounces shest switch, i. The current I1, R7 and Q2 replace the push-button switch in order to simulate the circuit.

As long as output is enabled which it is – pin 1 is Low For this latch to hold data, you must do the following: Here is the Link for the datasheet kindly take a look at the electrical characterstics, hope this helps. Place data on input pin 3 – i.

Choosing IC with EN signal 2. The following two tabs change content below. Compare latch based and register based design 5.

Last edited by KerimF; 27th August at It doesnt latch in HIGH state. AF modulator daha Transmitter what is the A? This single chip solution plus solenoid drivers worked very well I have 5V on D, but only get 3.

Do I need pull up resistors or does this sound like bad chips. Dec 248: Similar for other switch input. But when the OE is high the output will be in a high impedance state. Results 1 to 20 of
