 Ameya said: (Sep 14, 2011) 7411IC contains 14 pins. out of which 1 is +vcc and 1 is gnd .now left 12 pins. one AND gate requires 3 pins (2 for i/p and 1 for o/p).so there should be 4 AND gates. 2 on one side and 2 on other side.

So 3 AND gates.

 Ram said: (Jul 24, 2013) We required four and gates but your answer is three gates why?

 Faiz Ahmed Khan said: (Oct 4, 2015) This is wrong answer. It has 4 gate. I know it practically.

 Rocher said: (Jul 16, 2016) 7411 IC is 3 input and gate. Check for the pin diagram you all know about it.
