There we can see that the NAND gate gives a high output to all the input states except the input states 1,1.

This circuit is as basic as cv4011 gets for a NAND gate circuit and it demonstrates all the possible input values that a NAND gate chip can receive and output.

First and foremost, we must give power to the NAND gate chip. When a pushbutton is pressed down, the pushbutton now makes contact across to ground. When the doors are open the gate c4011 will be 1 and the output of the ic 0 which will turn the bulb off.

For this circuit, we will connect pushbuttons to the 2 inputs of the NAND gate. The pinout of the is shown below, so that you can see how to connect it in the circuit. Now let us see how this Integrated circuit works and how can we use it for our operations. The positive terminal of the battery was connected to the pin 14 and negative terminal of the battery was connected to the pin7. These resistors function as pull-up resistors.

Latest posts by Frank Donald see all. Each output can deliver output current of about 10mA at 12V but this range can reduce as the power supply voltage reduces. The output pins of the IC are 3,4,10,11 and input pins are 1,2,5,6,9,8,12, Below is the breadboard schematic version of the above circuit so that you can see the exact wiring of the circuit to the chip.

We can see the state of the output pins with the assigned inputs in the truth table given above. This way, we can see what combinations of inputs will make the NAND gate be off and what inputs make it turn on. This makes the bulb to glow indicating that the door is not properly shut. Thus, we can test out all logic levels. Closing a door will input level 0 and output level 1 causing bulb to light.

When we press down on a pushbutton, it changes to a logic level of LOW. Notify of all new follow-up comments Notify of new replies to all my comments. This IC was used since it withdraws only small power and also reduces the complexity of the circuit.

The quad NAND gate chip can be obtained very cheaply from a number of online retailers for just a few cents. The following two tabs change content below. The combined action of the these four gates form the working of this IC CD The resistors also keep Vcc from directly shorting to ground when the pushbutton is pushed down.

Let me tell you why, usage of large range of the NAND gates occupies more space and also it withdraws more power arising problems in power management to a circuit. Quote and Order boards in minutes on: Each NAND gate has two inputs and one output.

And these situations comprise all the situations that can arise for a 2-input NAND gate. When the door was closed push button switch, it apply logic 1 to the gate input. If the door was open or it is not properly shut, logic 0 is applied to the gate input. Frank Donald June 14, 1 Comment.

However, it is a very popular chip and many electronics parts suppliers have them. Here in this cd401 the input pins of the are connected to the supply voltage directly as shown in the diagram.

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

Each NAND gate has input pins and 1 output pin. In our circuit, we will use both dc4011 these cases. Video games, blogging and programming are the things he loves most.
