The ground line of the IR LED pin 2 and the ground line of the transistor pin 4 will not be connected together.

Latch-up circuit using 555 and opto-coupler

But when the Logic input is made high, this high voltage should be a minimum of 1. Out of which the Phototransistor mode is mostly used, so let us look at that mode first. Clap switch December 18, I hope you could help me with that. The output will not get high as soon as the input logic is made low and vice versa.

HiFirst of allthank you for your circuit above.

IC MCT2E Optocouplers, datasheet and pin description.

Digital object counter DIY kit September 1, It is normally not used for transistor mode, but will be used in diode mode. Another important parameter to consider while using an Optocoupler, is the rise time tr and fall time tf. Astable mode of timer. Dark sensor on breadboard September 8, How to use a relay November 15, Then Pull high the collector pin of the transistor using a resistor here I have used 1K and connect the collector pin to the output of your desired logic circuit.


This disables the alarm. This is where the isolation occurs.

The Emitter pin 4 is grounded. How to use variable resistors November 15, This IC is used to provide electrical isolation between two circuits, one part of the circuit is connected to the IR LED and the other to Photo-transistor.

Building a circuit on a breadboard November 8, From Latch up circuit using and optocouplerJuly 16, The digital signal given to the IR LED will be reflected on the transistor but there will be no hard electrical connection between the two. Review of PCBWay after-sale service. Submitted by admin on 7 March The complete working can also be understood form the GIF file above.

IC MCT2E Optocouplers

How to make one transistor FM transmitter on a stripboard- page I made this project with another opto-coupler, PC and it works well. The below waveform shows the time taken for the output to transit from one state to another. uc

When switch S2 is pressed, the base of the transistor connects to the ground 0V and resets the timer bringing Pin 4 to LOW state. Auto-Detection l Bluetooth l Smart Multimeter. How to use Mhz RF transmitter and receiver modules with arduino June 14, Easy steps for making a line following robot using Infrared LED, The transistor gets base bias via phototransistor and resistor R6 R.


The components kct2e selected in such a way that the frequency output of the astable circuit lies within the audio range. Connected to isolated ground. This comes in very handy when you are trying to isolate a noisy signal from your digital electronics, so if you are looking for an IC to provide optical isolation in your circuit design then this IC might be the right choice for you.

TL — Programmable Reference Voltage. In the Photo-transistor mode we will not be using the base pin pin 6 of the transistor; we just have to connect the anode pin of the Mct2ee LED pin 1 mct2d the logic input which has to be isolated and the cathode pin 2 of the IR led to the ground. Base pin of the Transistor.
