CD4049 DATASHEET PDF

The main use of this IC is to create a voltage multiplier circuit by simply adding resistor, capacitor, and diode with it. File:CMOS diagram. A technical drawing of the standard CMOS integrated circuit, including pinout information and internal gate schematics. The square wave oscillator circuit consist one resistor and capacitor and IC with it. Supply current 50mA max. As input voltage increase from 5v to 15v, output current sink also vary from 1.

Previous Post Basic pulse generator using op amp IC Circuit that use to illuminate your cupboard or other such dark places have significant application because main connection is not possible in those areas. When an electric signal is applied to the input pin of speaker, it generates sound waves. CD — Hex Buffer, Inverter 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. The Lamp in the above circuit will be ON for about two minutes with the given components before getting auto shut off.

C 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, c4d voltage at the point where four inverters are connected parallel becomes high thus switching off the lamp.

Latest posts by Frank Donald see all. Skip to main content. Step-By-Step 1 reads. Please see these circuits use CD as base:: When light is falling on LDR, its resistance gets very low and as a result input at pin 14 will be high. As input voltage ccd from 5v to 15v, output current sink also vary from 1.

The other pin is connected to ground. Choosing Battery for Robots. Virgin Galactic — Commercial Space Flight. Choosing Motor For Robots. What would be the average current in such a case? Learn how your comment data is processed. Quote and Order boards in minutes on: CD contain six inverter gates in one package as shown in diagram.

Thus a particular value of resistor, for fixed voltage, limits the current through it. The resistance decreases as the intensity of incident light increases, and vice versa.

This site uses Akismet to reduce spam. Reuven Saar 10 Dec Reply. The output frequency is relatively constant, the rate of change in frequency of the power supply voltage is less. So, apart from homes, it can also be used shop and banks. Many electronics circuits and projects for learning in simple ways. Also you can drive two TTL loads with it.

To understand the working you should know about the truth table of NOT gate which is: Magic eye can be used as automatic guest indicator in your home. It is used for interfacing and to make simple clock pulse generators and oscillators. This high-density System-in-Package SiP integrates dd, power switches, and support components.

This circuit uses a simple battery to power the light and also built with a auto shut-off. It can also used as a prevention measure against vandalism. The supply voltage to be used in the circuit have ranged from 3v to 12v of DC voltage. Quote and Order boards in minutes on https: When the switch S1 is momentarily pressed the voltage across the capacitor rises to 6v almost instantaneously.
