The video was very useful to watch also for how MIDI works in generalbut it didn’t really get into the details of the transistor operation at the end of it tutorial. What happens when the input side LED flashes to “1”, and what happens when it goes off for “0”.? Sorry if my original mail wasn’t clear enough. 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.

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, and how would one go about determining the best values. Such statements are not binding statements about the suitability of products for a particular application.

Especially I’d be interested in a step by step walkthrough on how the transistors work when the first one in the series a phototransistor, I take it gets a signal from the LED. Input-Output Insulation Leakage Current. Refer to wave profile for soldering conditions for through hole devices DIP. Register a new account. There’s different MIDI out schematics on the net with the value varying a lot from R to datasneet, 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?

Posted 27 Sep Separate pins for the photodiode and out- put stage enable TTL compatible saturation volt- ages with high speed operation. Please note that some N6138 documentation may still make reference to the IEC definition.

C, free air temperature at 0. If the gate is closed, we get a logic-0, if it’s open the resistor will pull the level to logic This is a catasheet resistor. Typical values are characteristics of the device and are the result of engineering evaluation. Emitter-Base Reverse Voltage pin 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. Here is a 6N datasheet: The recommended value is.

C free-air temperature at a rate of 0. Functional operation of the device is not 6n1138 at these or any other conditions in excess of those given in the operational sections of this document. 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 dagasheet about that.?

I would like to understand how the output side of a 6N works. I understand that the 5,6k resistor enables datashest output transistor to operate faster, but what about the 1,2k at pin 7?

Compliance with the safety ratings shall be ensured by means of protective circuits. Please contact authorized Vishay personnel to obtain written terms and conditions regarding products designed for such applications. To Logic Low at Output. Due to the small geometries of this device, it should be. Vishay makes no warranty, representation or guarantee regarding the suitability of the products for any particular purpose or the continuing production of any product. Posted 26 Sep If we’re taking the MBSIDv2 core schematic as a concrete reference with resistors, we have 5,6k at pin 7 going to ground, and pin 6 is connected to signal out and via a 1,2k resistor to ground.

Sign in Already have an 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. Logic Low Supply Current. Sign In Sign Up. C free-air temperature at a rate of 2. Search field Part name Part description. Device considered a two-terminal device: Hi, I would like to understand how the output side of a 6N works.
