In our circuit, we will use both of these cases. When either one or both of the pushbuttons are pressed, the NAND gate will output a logic HIGH or 1and the load connected to output will be powered on. This circuit is as basic as it gets for a NAND gate circuit and it demonstrates all the possible input values that a NAND gate chip can receive and output.

The combined action of the these four gates form the working of this IC CD The quad NAND gate chip can be obtained very cheaply from a number of online retailers for just a few cents.

The positive terminal of the battery was connected to the pin 14 and negative terminal of the battery was connected to the pin7. This way, we can see what combinations of inputs will make the NAND gate be off and what inputs make it turn on. The corresponding input pin will now be grounded and its logic level will change to a logic LOW now that it makes contact down to ground.

Closing a door will input level 0 and output cr4011 1 causing bulb to light. If the door was open or it is not properly shut, logic 0 is applied to the gate input. Latest posts by Frank Donald see all.

How to Build a NAND Gate Logic Circuit Using a 4011 Chip

Here in this circuit the input pins of the are jc to the supply voltage directly as shown in the diagram. And these situations comprise all the situations that can arise for a 2-input NAND gate.

The resistors also keep Vcc from directly shorting to ground when the pushbutton is pushed down. This makes the gate to change its output state from low to high.

N4 was wired independently and there is no dependency on other gates. Each NAND gate has two inputs and one output.

Quote and Order boards in minutes on: Frank Donald is an Electronics and Communication Engineer if loves building stuff in his free time. Frank Donald June 14, 1 Comment. We can see the state of the output pins with the assigned inputs in the truth table given above.

When a pushbutton is pressed down, the pushbutton now makes contact across to ground. Video games, blogging and programming are the things he loves most.

Each NAND gate has xd4011 pins and 1 output pin.

When the doors are open the gate inputs will be 1 and the output of the ic 0 which will turn the bulb off. Thus, the pushbuttons, when left alone, unpressed, will normally have a logic value of 1. However, it is a very popular chip and many electronics parts suppliers have them. These resistors function as pull-up resistors. One place it can be obtained from is Tayda Electronics at the following link: So the LED will turn on in this case.

First and foremost, we must give power to the NAND gate chip. There we can see that the NAND gate gives a high output to all the input states except the input states 1,1. This establishes power to the chip. For this circuit, lc will connect pushbuttons to the 2 inputs of the NAND gate.
