Thus, we can test out all logic levels.

A Beginner’s Guide To The Cmos

This way, we can see what combinations of inputs will cx4011 the NAND gate be off and what inputs make it turn on.

When the doors are open the gate inputs will be 1 and the output of the ic 0 which will turn the bulb off. Quote and Order boards in minutes on: This circuit is as basic as cr4011 gets for a NAND gate circuit and it demonstrates all the possible input values that a NAND gate chip can receive and output.

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. We can see the state of the output pins with the assigned inputs in the truth table given above. One place it can be obtained from is Tayda Electronics at the following link: The quad NAND gate chip can be obtained very cheaply from a number of online retailers for just a few cents.

For this circuit, we will connect pushbuttons to the 2 inputs of the NAND gate.

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

Thus, the pushbuttons, when left alone, unpressed, will normally have a logic value of 1. Now let us see how this Integrated circuit works and how can we use it for our operations. As a result the the bulb will not glow due to low output obtained from the output pins of the gates. The combined action of the these four gates form the working of this IC CD Video games, blogging and programming are the things he loves most.

In our circuit, we will use both cx4011 these cases. Each output can deliver output current of about 10mA at 12V but this range can reduce as the power supply voltage reduces.

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

Below is the jc schematic version of the above circuit so that you can see the exact wiring of the circuit to the chip.

First and foremost, we must give power to the NAND gate chip. When we press down on a pushbutton, it changes to a logic level of LOW. The positive terminal of the battery was connected to the pin 14 uc negative terminal of the battery was connected to the pin7.

How to Build a NAND Gate Logic Circuit Using a Chip

So the LED will turn on in this case. This establishes power to the cs4011. However, in this circuit, we will just use one NAND gate, to make the circuit as simple as possible.

The following two tabs change content below. 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 cc4011. The pinout of the is shown below, so that you can see how to connect it in the circuit.

Practical Electronics/IC/4011

This IC was used since it withdraws only small power and also reduces the complexity of the circuit. When either one or both c4d011 the pushbuttons are pressed, the NAND gate will output a logic HIGH or 1and the load connected to output will be powered on. If the door was open or it is not properly shut, logic 0 is applied to the gate input.

There we can see that the NAND gate gives a high output to all the input states except the input states 1,1. These resistors function as pull-up resistors. Each NAND gate has input pins and 1 output pin. Closing a door will input level 0 and output level 1 causing bulb to light.
