CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. Copyright © , Texas Instruments Incorporated. The basic building block of the circuit made around a very well known IC CD which is a hex inverter. This can be constructed, with the. the inverter CMOS digital IC datasheet is IC Hex Inverting Buffer IC, to design the Square wave oscillator generator circuit diagram.

In this 1 is for supply voltage and pin is connected to ground and pin 13 and 16 are unused xd4049. To sum up when the switch is pressed and released, the lamp lights up. Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time.

And for a larger lamp current, a transistor switch should be used in place of parallel connected inverters. It also used for the conversion of high logic levels to low. Resistor Resistor is a passive component used to control current in a circuit.

IC Hex inverter Datasheet – Square wave oscillator

It can also be useful in making various projects like simple LED torch light, Automatic Street light, magic eye, and automatic guest detector at home door. The Lamp in the above circuit will be ON for about two minutes with the given components before getting auto shut off. This under cupboard lighting circuit will be a great alternative for traditional torches and also proves to be cost effective among all other lighting systems.


SPI Module of Arduino. I need to build a circuit contain a crystal oscillator square wave with The main use of this IC is to create a voltage multiplier circuit by simply adding resistor, capacitor, and diode with it.

Magic Eye Circuit Using 4049 IC

Could you please be specific re the frequencies — I need a variable range of 1. The following two tabs change content below.

Reuven Saar 10 Dec Reply. This site uses Akismet to reduce spam.

Touch switch using monostable mode of timer IC. Leave a Reply Cancel reply. Choosing Battery for Robots. When an electric signal is applied to the input pin of speaker, it generates sound waves. The IC consists of six NOT gate inside it and having a high input supply voltage with a maximum current rating of 1mA at 18v.

Quote and Order boards in minutes on https: The 2D dimension will help you in using this IC on breadboard or perf board. The circuit we use a little equipment, just add a resistor and capacitor are the only one, It uses less energy. The input-signal high level VIH can exceed the VCC supply voltage when these devices are used for logic-level conversions. Notify of all new follow-up comments Notify of new replies to all my comments. Light detector using LDR and astable mode of timer.

This high-density System-in-Package SiP integrates controller, power switches, and support components. Speaker A loudspeaker or “speaker” is a transducer that converts electrical energy into acoustical energy. Magic eye can be used as automatic guest indicator in your home. Interface SD Card with Arduino.


CD4049 – Hex Buffer, Inverter

I have the circuit but i need for efficient pulse generator with a variable resistor to control the trigger speed to the thyristor gate. Arduino based GPS receiver.

Oc of this magic eye circuit is very simple as we know LDR has a characteristic that its value of resistance depends on the amount of light falling on it means it shows very high resistance of about 1 Mega ohms in darkness but a resistance of few kilo ohms in light here we utilize this phenomenon to make magic eye.

Also you can drive two TTL loads with it.

Magic Eye Circuit Diagram Using IC

The resistance decreases as the intensity of incident light increases, and vice versa. Virgin Galactic — Commercial Space Flight. The supply voltage to be used in the circuit have ranged from 3v to 12v of DC voltage. The frequency determined by the resistor R1 and capacitor C1 can be obtained by the formula below: It can also used as a prevention measure against vandalism.

What would be the average current in such a case? Learn how your comment data is processed. We will receive logic zero at output pin therefore LED and buzzer connected at output will not sound. Video games, blogging and programming are the things he loves most.
