IC CD4049 PDF

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.

A loudspeaker or “speaker” is a transducer that converts electrical energy into acoustical energy. Its resistance is given by the ratio of voltage applied across its terminals to the current passing through it. An LDR Light dependent resistoras its name suggests, offers resistance in response to the ambient light.

Hex Inverter Buffer IC pinout, Features, Equivalent & Datasheet

Thus a particular value of resistor, for fixed voltage, limits the current through it. Quote and Order boards in minutes on: Learn how your comment data is processed.

Just install this at the bottom of the door and whenever a person would arrive, his shadow will fall on the circuit giving an indication that somebody is present on the door without the knowledge of the visitor. CD contain six inverter gates in one package as shown in diagram.

Also — an amplitude of 9 volt. So, apart from homes, it can also be used shop and banks. Resistor Resistor is a passive component used to control current in a circuit. In this 1 is cd40449 supply voltage and pin is connected to ground and pin 13 and 16 are unused pin.

Connect two in series to make a non-inverting buffer.

CD4049 – Hex Buffer, Inverter

cx4049 And for a larger lamp current, a transistor switch should be used in place of parallel connected inverters. Cupboard Lighting Circuit Circuit that use to illuminate your cupboard or other such dark places have significant application because main connection is not possible in those areas.

The square wave oscillator circuit consist one resistor and capacitor and IC with it. Light detector using LDR and astable mode of timer. Pls i will need a help in building my own inverter.

Magic Eye Circuit Using 4049 IC

Note that when the lamp is ON the lamp current would be flowing through the conducting output stages of these inverters inside the IC. The circuit we use a little equipment, just add a resistor and capacitor are the only one, It uses less energy.

In the absence of light, LDR exhibits a resistance of the order of mega-ohms which decreases to few Skip to main content. Working 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 cd049 to make magic eye.

As input voltage increase from 5v to 15v, output current sink also vary from 1. Quote and Order boards in minutes on https: The frequency determined by the resistor R1 and capacitor C1 can be obtained by the formula below:.

In this circuit, we are utilizing only 1 gate of IC. Now the capacitor C1 has already started discharging through resistor R1 and the moment voltage across it decreases to a value that is treated as LOW state, the voltage at the point where four inverters are connected parallel jc high thus switching off the lamp.

When light is falling on LDR, its resistance gets very low and as a result input at pin 14 will be high.

But as soon as shadow falls on LDR, its resistance will go high. The other pin is connected to ground.

Supply current 50mA max. To sum up when the switch is pressed and released, the lamp lights up. When an electric signal is applied to the input pin of speaker, it generates cf4049 waves. Metronome using astable mode of timer IC.
