The pinout of the is shown below, so that you can see how to connect it in the circuit.

Below is the breadboard schematic version of the above circuit so that you can see the exact wiring of the circuit to the chip. Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time. However, it is a very popular chip and many electronics parts suppliers have them. When the doors are open the gate inputs will be 1 and the output of the ic 0 which will turn the bulb off.

This establishes power to the chip. Thus, the pushbuttons, when left alone, unpressed, will normally have a logic value of 1.

This IC was used since it withdraws only small power and also reduces the complexity of the circuit. When we press down on a pushbutton, it changes to a logic level of LOW. So the LED will turn on in this case.

This way, we can see what combinations of inputs will make the NAND gate be off and what inputs make it turn on. Here in this circuit the input pins of the are connected to the supply voltage directly as shown in the diagram. One place it can be obtained from is Tayda Electronics at the following link: This circuit was wired as a door open indicator which indicates the opening dd4011 door using the bulb which id connected to the output pins of the gates.

Each NAND gate has input pins and 1 output pin. However, in this circuit, we will just use one NAND gate, to make the circuit as simple as possible. The positive terminal of the battery was connected to the pin 14 and negative terminal of the battery was connected to the pin7.

The resistors cdd4011 keep Vcc from directly shorting to ground when the pushbutton is pushed down.

Latest posts by Frank Donald see all. This makes the bulb to glow indicating that the door is not properly shut. This makes the gate to change its output state from low to high. The quad NAND gate chip can be obtained very cheaply from a number of cd40011 retailers for just a few cents. The output pins of the IC are 3,4,10,11 and input pins are 1,2,5,6,9,8,12, Now let us see how this Integrated circuit works and how can we use it for our operations.

First and foremost, we must give power to the NAND gate chip. For this circuit, we will connect pushbuttons to the 2 inputs of the NAND gate. As a result the the bulb will not glow due to low cd0411 obtained from the output cd4101 of the gates. Quote and Order boards in minutes on: The combined action of the these four gates form the working of this IC CD In our circuit, we will use both of these cases. If the door was open or it cd411 not properly shut, logic 0 is applied to the gate input.

Frank Donald June 14, 1 Comment. 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 xd4011 be powered on. Thus, we can test out all logic levels. The following two tabs change content below.

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. Notify of all new follow-up comments Notify of new replies to all uc comments. N4 fd4011 wired independently and there is no dependency on other gates. When the door was closed push button switch, it apply logic 1 to the gate input.

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. We can see the state of the output pins with the assigned inputs in the truth table given above.

And these situations comprise all the situations that can ix 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. Each output can deliver output current of about 10mA at 12V but this range can reduce as the power supply voltage reduces.

When a pushbutton is pressed down, the pushbutton now makes contact across to ground. There we can see that the NAND gate gives a high output to all the input states except the input states 1,1. Closing a door will input level 0 and output level 1 causing bulb to light.

Video games, blogging and programming are the things he loves most. These resistors function as pull-up resistors. Each NAND gate has two inputs and one output.
