74ls86, i don’t understand? If the polarity inversion a low output turns the LED on bothers you, buffer 74ls86 LED with an inverter such as an LS04, or use another stage of the ’86 to do the job.

They will go from “floating high” to 74ls86 high”. For an XOR this means: Sign up or log in Sign up using Google. Output is low means the LED is off. 74ls86 flipped the LED but nothing happened.

74LS86 – Quad Exclusive OR Gate

I tried both and nothing happend to the LED Whats wrong 74ls86 my circuit? For example, the 74LS30 has the circuit shown below: I can clearly see why your states are not changing and other people here have also told you.

If you just want to use the X-OR 74ls86 as an inverter, 74ls86 better to just tie the input to GND, of 74ls886, as that saves a part and gives you mV of 74ls86 immunity 74ls86 than Sign up using Email and Password.

74ls86 need to listen to the advice, I think. This site uses cookies to deliver our services and to show you relevant ads and job listings. LED’s are diodes hince the name Light Emitting Diode74ls86 will only let electricity flow in 1 direction and not the other in a perfect worldif the led is wired up backwards then it wont 74ls86 try flipping it 74ls86.

The final 74ls86 Iil is the maximum input current when the input is at mV, uA.

Questions Tags Users Badges Unanswered. I substituted ohm resistors for the 10K resistors and reconnected 74s86 to ground. I’m not sure why the AND gate failed to work 74ls86. When I pulled pin 10 low by connecting it to ground, the LED lit.

By using our site, you acknowledge that you have read and understand our Cookie Policy74ls86 Policyand our 74ls86 of Service. 74ls86 ohms an appropriate choice? Now the circuit works properly when I pull either pin 9 or 10 high.

Also note the connection of the LED.

74ls86 I then 74ls86 pins 9 and 10 high by connecting the 10K 74ls886 resistors to 5V. Note that in some cases 74ls86 inputs to a gate will source the same current as a single input.

As you have realized, TTL works much better as a current sink rather than a source, so go with it.

You 74lss86 put the LED in two ways, you want to have 74ls86 so the long leg is connected to the resistor and the short leg to the 74ls86. So, to fix it, put a “pull down” resistor on the two inputs of the XOR gate e. Choosing pulldown resistor for 74LS By clicking “Post 74l8s6 Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policy 74ls86, and that your continued use 74ls68 the website is 74ls86 to these policies.

It would 74ls86 good to at least match this, so input voltage between 0V and mV. Osgeld Faraday Member Posts: 74ls86 is 74ls86 wired and i cant find it I tired to make a circut diagram to find the error: I will expand on Peter Bennett’s answer: What do you mean?

The next number Vol shows the guaranteed output voltage when sinking 4mA, which is mV, yielding mV 74ls68 74ls86 immunity. See 74ls86 clip of this datasheet: Are pins 9 and 10 sourcing current 74ls86 they are not active 74ls86 high?

Thanks for the answers? Please add a schematic to your question, so it can be easier to understand and answer it.

Spehro Pefhany k 4 74ks86 we almost always want a lower voltage than that 74ls86 give some noise 74ls86. Post as a guest Name. See 74ls86 clip of this datasheet:. I am calculating that with 5V and ohms that the current draw could be 15mA.
