Does changing the gate number have any effect on the output.I had placed 7400N as NAND with 1,0 as input but I didn't got the output.pls help

what is the name of the component that you placed in front of the output of each gate?

It's a probe

Some hints. It has come out that if this device does not work, its testing might be difficult. So build and test at first only the resistor chain and the comparator stage. The signals A3A2A1 should be with small values of Vin, A3A2A1 = 000. When you add Vin, you get next A3A2A1 = 001. With even larger Vin you get next A3A2A1 = 011. Finally, with largest Vin (do not try more than Vin = 5V) you get A3A2A1 = 111.You should adjust the positive supply V+ so that the 1-values of A3A2A1 are about 5V. If the low values are too much on negative side (so that the Decoder does not work), you could try to adjust the negative supply, V-, nearer to zero (value -1V should work). Also, it is an excellent idea to connect diodes (and suitable limiting resistors as 300 Ω) to the 741-outputs A3A2A1 so that you can easily see, if the circuit works. When the resistor-chain and the comparator stage works properly, connect the signals A3A2A1 to Decoder inputs 5,6,7 (pins 2,3,4) in this order. Connect the input 4 and EI (pins 1 and 5) to ground (0V). The output pins A1 and A0 (pins 7,9) in this order correspond to schematic signals Y1Y0. You can connect diodes to output pins A1 and A0 also.   can you built this

You you know why the output of these gates are 5V? Shouldn't them be 4.3V because of the drop of the output transistor? Even when I put a potentiometer from the output to the ground and bring it to 0 Ohms, it doesn't change from 5V. I wonder if Multisim is just wrong.

thanks a lot. I realized I was setting up the VCC and ground in a wrong way. You showed me the correct way. I appreciate it.

vcc is the +ve terminal while ground is -ve

by dc power, i presume, you mean dc voltage source. vcc is a dc voltage source. dc voltage is supplied to the circuit using either vcc or a dc source like a battery.
