Results 1 to 20 of The led in the circuit is always Off. It doesnt latch in HIGH state.

Can anyone please help me sort out the problem?. Datasheet of 74LS is also attached. Last edited by sharikbaig; 27th August at 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.

As long as output is enabled which it is – pin 1 is Low For this latch to hold data, you must do the following: Enable gates pin 11 high 2. 7ls373 data on input pin 3 – i. You have LE fixed High, hence output equals input Need to either set LE low to latch the input or choose different latch.

Similar for other switch input. The only potential issue is both switches operating together as the 74ls73 becomes indeterminate. If you like I will draw the schematic for you. Last edited by KerimF; 27th August at Being not a machine, I always do silly mistakes or miss important things.

Therefore almost every post I write would usually be updated several times till it reaches its saturation: Also I may not reply at time. Our main server could be out of service anytime.

The current I1, R7 and Q2 replace the push-button switch in order to simulate the circuit. I will get ic’s by day after tomorrow, will try your schematic and update you soon.

Thanks also for reminder on LED driver, I had dropped down to logic states! You people are very helpful, Thanks. Any other idea is also welcomed.

Help with Latch IC 74LS based latching ciruit I actually made a similar project back in the 80’s when experimemting with programmable logic the good old days!

Each momentary switch would latch a solenoid valve and when activated switch off the others valvesa bit like a manual washing machine. This single chip solution plus solenoid drivers worked very well It could have been a useful touch switch which weren’t very common thenbut I learnt how to filter out, clamp and provide immunity instead! These datasbeet chips were 18 or 24 pins?
