CD contain six inverter gates in one package as shown in diagram. In this circuit, we are utilizing only 1 gate of IC. Arduino based GPS receiver.

The output frequency is relatively constant, the rate of change in frequency of the power supply voltage is less. This high-density System-in-Package SiP integrates controller, power switches, and support components.

Connect two in series to make a non-inverting buffer. Abdelmoniem Mohamed Abdelaty 18 Dec Reply.

CD4049 – Hex Buffer, Inverter

ix It also used for the conversion of high logic levels to low. The circuit is built around a single vd4049 inverting buffer IC CD which consists of six inverter gates in one package as shown in the below diagram.

As input voltage increase from 5v to 15v, output current sink also vary from 1. Also — an amplitude of 9 volt. Circuit that use to illuminate your cupboard or other such dark places have significant application because main connection is not possible in those areas.


Metronome using astable cdd4049 of timer IC. A loudspeaker or “speaker” is a transducer that converts electrical energy into acoustical energy. Submitted by webmaster on 26 December Notify of all new follow-up comments Notify of new replies to all my comments. In this 1 is for supply voltage and pin is connected to ground and pin 13 and 16 are unused pin.

Magic Eye Circuit Using 4049 IC

Supply current 50mA max. Just install if 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.

Latest posts by Frank Donald see all. A speaker is commonly used And rest of the inverters in the CD IC are connected parallel together for lighting the lamp connected to the circuit.

Hex Inverter Buffer IC pinout, Features, Equivalent & Datasheet

The supply voltage to be used cd0449 the circuit have cd409 from 3v to 12v of DC voltage. TL — Programmable Reference Voltage. The circuit we use a little equipment, just add a resistor and capacitor are the only one, It uses less energy. The Maximum power supply must not exceed 18 volts. The other pin is connected to ground. 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 becomes high thus switching off the lamp.


The resistance decreases as the intensity of incident light increases, and vice versa.

Learn how your comment data is processed. When the switch S1 is momentarily pressed the voltage across the capacitor rises to 6v almost instantaneously. They are omnipresent in Frank Donald March 3, 0 Comments.

IC Hex inverter Datasheet – Square wave oscillator

The main use of this IC is to create a voltage multiplier circuit by simply adding resistor, capacitor, and diode with it. Interface GPS with Arduino. Group all Htabs Electronics.

Resistor Resistor is a passive component used to control current in a circuit. Speaker A loudspeaker or “speaker” is a transducer that converts electrical energy into acoustical energy. It is used for dc4049 and to make simple clock pulse generators and oscillators. Its resistance is given by the ratio of voltage applied across its terminals to the current passing through it.
