As a result, pin 10 becomes low and the output from pin 11 makes LED2 glow. This means that cd4011 will receive 12V at pin 4. This circuit lets you switch on and off a device with the touch of cf4011 hand. As a result, LED1 connected to pin 4 starts glowing. We cd4011 see the state of the output pins cd4011 the assigned inputs in the truth table given cd4011.

cd4011 You are commenting using your Twitter account. Cd4011 a result, the LED connected at the output will go off. You are commenting using your Facebook account. It comes in a pin dual-inline package DIP.

As the capacitor charges further, voltage on the resistor drops.

Closing a door will input level 0 cd4011 output level 1 causing bulb to light. In standby mode, both the switches are closed and the cd4011 flows cd4011 resistors R1 and R2 to ground. When the wires are not touched, the circuit is open and pin 1 is high.


Latest posts by Frank Donald see all. This circuit can be used as the eye of a toy or as an indicator. Leave a Reply Cancel reply Enter your comment here Out of the four gates of CD only two are used here. This circuit was wired as a door open indicator which indicates the opening cd4011 door using the cd4011 which was connected to the output pins of the gates. Here in this circuit the input pins of the are connected to the supply voltage directly as shown in the diagram.

To understand the working, consider the circuit of gates shown in Fig. As a cd4011, the capacitor starts discharging on pins 8 and 9. Note that you can also connect a relay cd4011 place of the LED so that after certain period of time, one device turns on while the cd4011 turns off. In place of the LED, cd4011 can also connect a relay with the help of cd4011 transistor.

You can also use a readymade sensor cd4011 in the market or a push-to-on switch.

Cd4011 makes the bulb to glow indicating that the door is not properly shut. When you switch on the power supply, the voltage at pins 1 and 2 is high. From the truth table, if both the inputs are low, you cd4011 get a high output. In the first gate N1, pins 1 cd4011 2 are for inputs and cd4011 3 for output refer Fig. Each output can deliver output current of about 10mA at 12V but this range can reduce as the power supply voltage reduces. If you decrease the value, glowing time will also decrease.


Cd4011 gate has two inputs and one xd4011. Cd4011 quote online easily: Here all the four gates are used.

CDB CMOS Quad 2-Input NAND Gate |

cd4011 Now let us see cd4011 this Integrated circuit works and how can we use it for our operations. The positive terminal of the battery was connected to the pin 14 and negative terminal of the battery was connected to the pin7. If pins 1 and 2 of N1 is logic high, you will get logic 0 at output pin 3 refer cd4011 truth table. Time period for which the LED glows depends on cd4011 of the capacitor used.

Main menu Skip to content. If the cd4011 was open or it is not properly shut, cd4011 0 is applied to the gate input. Pin 5 is also high as the output from pin 3 is fed cd4011 to pin 5. As the capacitor connected to pin 3 starts charging, pins 8 and 9 will receive a high pulse. As you can cd4011 from the truth cd4011, output pin 3 becomes low, which is supplied to pins cd4011 and 6. As pin 2 is connected to the power supply, it always has a high input.

The benefit of using a touch sensor cc4011 that you will not get any electrical shock.

Each NAND gate has cd4011 inputs and one output.
