Why you don';t need a pull down resistor for the inputs? If I don't use a pulldown resistor for the inputs, the output has unexpected results. Thank you.
+Eduard Voicu you are right, you would need a pull down resistor for inputs when you actually use the gate in any application, but this tutorial was only showing the truth table of the XNOR gate on LED, so I didn't care about unexpected results or floating connections. Thank you :-)
You may wanna check this website: hyperphysics.phy-astr.gsu.edu/hbase/Electronic/xnor.html It has the schematic. If you still don't know how to implement it on a breadboard kindly contact me to make you a video. Email: admin@basseltech.com Kik: kik.me/basseltech/
so this turn out need an pull down resistor for working.That's how ic have some big disadvantages that the circuit made up with external components would be better.
It depends on your application. For commercial use, you should analyze your design both delay time wise and cost wise, to minimize both of them. Have a great day! :-)
BasselTech actually both pull up and pull down resistor solution can't solve the problem(it doesn't work properly),my application is needing an fast response about 100khz and not be delay or noise.,i'm going to burn it out in microwave.
+PD Engson Yes sir, you can use IC 74266 instead of IC 4077 and it has the same pin configuration and will work the same as illustrated in this video. :)
Highly recommended video👍
Thank you! Glad it helped! :-)

Please check my video when I wire a switch to a logic gate: ua-cam.com/video/EMPnha6wVac/v-deo.html
What about I use IC 7404, 7432, and 7408 together?

what project or device can i do using XNOR?
Nice work good job
Thank you, Naveen!
If you have any doubts, feel free to contact me.
Have a nice day! :-)

Nice bro bring more videos
Thank you bro! Stay tuned, more is coming soon. :-)
@@BasselTech bro i begg you please make an video on BUFFER logic gate please there is no tutorials in youtube on buffer logic gate
Can you do XNOR using 74LS266 IC ?
+PD Engson Yes sir, you can use IC 74266 instead of IC 4077 and it has the same pin configuration and will work the same as illustrated in this video. :)
@@BasselTech I disagree, since 74LS266 is Open Collector

what resistor huhu
It's a 220-ohm resistor used to connect the short leg of the LED to GND. Have a nice day! :-)
