Input Reverse Breakdown Voltage. 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.
If the gate is closed, we get a logic-0, if it’s open the resistor will pull the level to logic Here is a 6N datasheet: Share this post Link to post Share on other sites. Hi and 6h138, the links you provide are a bit more “fundamental” than what I had in mind, dealing with atom level operation electrons and holes 6n318 semiconductors, while I was looking for a more “mundane” explanation. I might be mistaken, but based on the video it seems that the second transistor see schematic in the first post functions just as a switch, switching between full saturation and whatever is the opposite of saturation: 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.
Typical values are characteristics of the device and are the result of engineering evaluation. Due to the small geometries of this device, it datashheet be handled with Electrostatic Discharge ESD precautions.

This is a pull-up resistor. High common mode 61n38 immunity and very high current ratio together with VAC insulation are achieved by coupling an LED with an integrated high gain photo detector in an eight pin dual-in-line package.
Separate pins for the photo diode and output stage enable TTL compatible saturation voltages with high speed operation. C free-air temperature at a rate of 2. Access to the base terminal allows adjustment to the gain bandwidth. Emitter-Base Reverse Voltage pin 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 so, the rating should be found on n6138 absolute maximum ratings section of the datasheet. Sign up for a new account in our community. The circuit that I have is the one below sorry that the image is a bit darkand 6n1138 question is what function do the resistors R1 and R2 serve, and how would one go about determining the best values.

I’ve tried R1 values for circuit below at R, 1k, 4. Please note that some Vishay documentation may still make reference to the IEC definition.

Device considered a two-terminal device: 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 daatasheet to signal out and via a 1,2k resistor to ground. 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.
Separate pins for the photodiode and out- put stage enable TTL compatible saturation volt- ages with high speed operation. Started by jjonas26 Sep I guess that you mean pin 6? 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 datxsheet only whether the voltage at pin 6 is high or low?

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.
