In our circuit, we will use both of these cases. The ccd4011 terminal of the battery was connected to the pin 14 and negative terminal of the battery was connected to the pin7.

Quote and Order boards in minutes on: Thus, we can test out all logic levels. As a result the the bulb will not glow due to low output obtained from the output pins of the gates.

Practical Electronics/IC/4011

Video games, blogging and programming are the things he loves most. Thus, the pushbuttons, when left alone, unpressed, will normally have a logic value of 1. N4 was xd4011 independently and there is no dependency on other gates. 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 cd40011 arising problems in power management to a circuit. For this circuit, we will connect pushbuttons to the 2 inputs of the NAND gate. When the door was closed push button switch, it apply logic 1 to the gate input.

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 my comments. When the doors are open the gate inputs will be 1 and the output of the ic 0 which will turn the bulb off. And these situations comprise all the situations that can arise for a 2-input NAND gate. There we can see that the NAND gate gives a high output to all the input states except the input states 1,1.

Latest posts by Frank Donald see all. This IC was used since it withdraws only small power and also reduces the complexity of the circuit.

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

We can see the state of the output pins with the assigned inputs in the truth table given above. The output pins of the IC are 3,4,10,11 and input pins are 1,2,5,6,9,8,12, Here in this circuit the input pins of the are connected to the supply voltage directly as shown in the diagram.

Now let us see how this Integrated circuit works and how can we use it dd4011 our operations.

However, in this circuit, we will just use one NAND gate, to make the circuit as cd411 as possible. This circuit is as basic as it gets for a NAND gate circuit and it demonstrates all the possible input values that a NAND jc chip can receive and output.

Each NAND gate has input pins and 1 output pin. 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 a pushbutton is pressed down, the pushbutton now makes contact across to ground. 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. The combined action of the these four gates form the working of this IC CD 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.

Each output can deliver output current of about 10mA at 12V but this range can reduce as the power supply voltage reduces. When we press down on a pushbutton, it changes to a logic level of LOW.
