Posted 27 Sep To Logic High at Output. This is a pull-up resistor. Refer to wave profile for soldering conditions for through hole devices DIP. Edited 26 Sep by jjonas. Photodarlington operation is achieved by tying the V. I’ve tried R1 values for circuit below at R, 1k, 4. I guess that you mean pin 6? Sign In Sign Up.

I understand that the 5,6k resistor enables the output transistor to operate faster, but what about the 1,2k at pin 7? Emitter-Base Reverse Voltage pin Using a resistor between pin 5 and 7 will decrease gain and delay time. Please note that some Vishay documentation may still make reference to the IEC definition.

The recommended value is. Logic High Supply Current. Register a new account.

But when the second transistor is fully saturated, it will practically suck up all the current, so one might think that the current limiter R1 size is in practice defined only by how much current the transistor can take.

There’s different MIDI out schematics on the net with the value varying a lot from R to 10k, even though the latter was on a 6N which might make a differenceso is it that the output current doesn’t really matter as long as it’s not too bigwhat matters is only whether the voltage at pin 6 is high or low?

Logic Low Supply Current. The MIDI specification gives a schematic only for PC optocoupler and mentions that 6N or others can be used with modifications, but doesn’t say what those modifications are.

If the gate is closed, we get a logic-0, if it’s open the resistor will pull the level to logic-1 Best Regards, Thorsten. Especially I’d be dwtasheet in a step by step walkthrough on how datashedt transistors work when the first one in the series a phototransistor, I take it gets a signal from the LED.

Posted 26 Sep Exposure to absolute maximum ratings for extended periods of the time can adversely affect reliability. Sign up for a new account in our community. Access to the base terminal allows adjustment to the gain bandwidth. Datashwet so, the rating should be found on the absolute maximum ratings section of the datasheet.

Hi and thanks, the links you provide are a bit more “fundamental” than what I had in mind, dealing with atom level operation electrons and holes of semiconductors, while I was looking for a more “mundane” explanation. Due to the small geometries of this device, it should be.

Here is a 6N datasheet:. Typical values are characteristics of the device and are the result of engineering evaluation. Device considered a two-terminal device: If the gate is closed, we get a logic-0, if it’s open the resistor will pull the eatasheet to logic Due to the small geometries of this device, it should be handled with Electrostatic Discharge ESD precautions.

C free-air temperature at a rate of 2. Search field Part name Part description. Input Reverse Breakdown Voltage. On the receiving end there is a R resistor to limit the current when the transistor is off and won’t let any current through, so I guess we don’t have to worry about that.?

Input-Output Insulation Leakage Current. Separate pins for the photo diode and output stage enable TTL compatible saturation voltages with high speed operation.

Dimensions in inches mm. Hi, I would like to understand how the output side of a 6N works. I guess R2 can be found out using an oscilloscope, to see which size enables the shortest propagation delay like explained in the video at this point.

The circuit that I have is the one below sorry that the image is a bit darkand my question is what function do the resistors R1 and R2 serve, catasheet how would one go about determining the best values. Derate linearly above Functional operation of the device is not datashret at these or any other conditions in excess of those given in the operational sections of this document.

Compliance with the safety ratings shall be ensured by means of protective circuits. Here is a 6N datasheet:
