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

So the LED will turn on in this case. The resistors also keep Vcc from directly shorting to ground when the pushbutton is pushed down. However, in this circuit, we will just use one NAND gate, to make the circuit as simple as possible.

For this circuit, we will connect pushbuttons to the 2 inputs of the NAND gate. Quote and Order boards in minutes on: Each NAND gate has two inputs and one output. Each NAND gate has input pins and 1 output pin.

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

This IC was used since it withdraws only small power and also reduces the complexity of iv circuit. The following two tabs change content below. When the doors are open the gate inputs will be 1 and the output of the ic 0 which will turn the bulb off.

First and foremost, we must give power to the NAND gate chip. When the door was closed push button switch, lc apply logic 1 to the gate input. The quad NAND gate chip can be obtained very cheaply from a number of online jc for just a few cents. There we can see that the NAND gate gives a high output to all the input states except the input states 1,1. However, it is a very popular chip and many electronics parts suppliers have them.

Here in this circuit the input pins of the are connected to the supply voltage directly as shown in the diagram. When a pushbutton is pressed down, the pushbutton now makes contact across to ground. Notify of all new follow-up comments Notify of new replies to all my comments. This establishes power to the chip. Video games, blogging and programming are the things he loves most.

Thus, we can test out all logic levels. Frank Donald June 14, 1 Comment. 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.

Closing a door will input level 0 and output level 1 causing bulb to light. Below is the breadboard schematic version of the above circuit so that you can see the exact wiring of the circuit to the chip.

The output pins of the IC are 3,4,10,11 and input pins are 1,2,5,6,9,8,12, 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. This makes the bulb to glow indicating that the door is not properly shut. The combined action of the these four gates form the working of this IC CD If the c4d011 was open or it is not properly shut, logic 0 is applied to the gate input.

And these situations oc all the situations that can arise for a 2-input Cd011 gate. Each output can deliver output current of about 10mA at 12V but this range can reduce as the power supply voltage reduces. 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.

Latest posts by Frank Donald see all. Now let us see how this Integrated circuit works and how can we oc it for our operations.

One place it can be obtained from is Tayda Electronics at the following link: Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time. As a result the the bulb will not glow due to low output obtained from the output pins of the gates. N4 was wired independently and there is no dependency on other gates.
