When the doors are open the gate inputs will be 1 and the output of the ic 0 which will turn the bulb off. If the door was open or it is not properly shut, logic 0 is applied to the gate input.

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

Here in this circuit the input pins of the are connected to the cc4011 voltage directly as shown in the diagram. 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.

The combined action of the these four gates form the working of this IC CD N4 was wired independently and there is no dependency on other gates. We can see the state of the output pins with the assigned inputs in the truth table given above.

These resistors function as pull-up resistors. Now let us see how this Integrated circuit works and how can we use it for our operations. However, it is a very popular chip and many electronics parts suppliers have them.

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. However, in this circuit, we will just use one NAND gate, to make the circuit as simple if possible.

The following two tabs change content below. There we can see that the NAND gate gives a high output to all the input states except ccd4011 input states 1,1.

Each output can deliver output current of about 10mA at 12V but this range can reduce as the power supply voltage reduces. Thus, we can test out all logic levels. Notify of all new follow-up comments Notify of new replies to all my comments.

This circuit was wired as a door open indicator which indicates the opening of door using the bulb which was connected to the output pins of the gates. Quote and Order boards in minutes on: Frank Donald c4d011 an Electronics and Communication Engineer who loves building stuff in his free time.

One place it can be obtained from is Tayda Electronics at the following link: When a pushbutton is pressed down, the pushbutton now makes contact across to ground. Below is the breadboard schematic version of the above circuit vd4011 that you can see the exact wiring of the circuit to the chip.

For this circuit, we will connect pushbuttons to the 2 inputs of the NAND gate. This makes the gate to fd4011 its output state from low to high. This establishes power to the chip. This makes the bulb to glow indicating that the door is not properly shut. And these situations comprise all the situations that can arise for a 2-input NAND gate.

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.

When we press down on a pushbutton, it changes to a logic level of LOW. This IC was used since it withdraws only small power and also reduces the complexity of the circuit. First and foremost, we must give power to the NAND gate chip. 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. As a result the the bulb will not glow due c4011 low output obtained from the output pins of the gates.

Thus, the pushbuttons, when left alone, unpressed, will normally have a logic value of 1.
