The H11L models have different guaranteed threshold currents: All of them are lc900v. Hosted by Nimbus Hosting. So the H11L1 is the original and the PC is the copy?
The documentation from says to use the 6N which I understand is an improved version of the rather poor specs 6Nbut I suspect may still be pc900vv poor choice today. Already have an account? As for the digital output: The differences in the different opto isolators are: Welcome to the Gearslutz Pro Audio Community!

Furthermore, any change in the amplification due to manufacturing variations or temperature effects is visible on the output. Remove this ad forever by registering!
New Reply Thread Tools. So you do not longer have to compute how much input current you need to be able to switch a certain output current, you just have to ensure that you are above pc90v threshold.
I’m the OP and realize this thread is old, but The H11Lx has an unusual pinout that makes pc900b incompatible with any other optocoupler. The H11L1 starts with an analog photodiode, but what makes it digital is the Schmitt trigger that ensures that the output is fully switched on when the input current goes above the turn-on threshold, and that the output pc90v completely off when the current goes below the turn-off threshold. So, seeing that the PC is no longer available at least not if you’re not willing to risk fakes on eBay etc.
PC MIDI opto-isolators and compatibles – Gearslutz
In the common and cheap phototransistor optocouplers, the receiver consists of nothing but a phototransistor, which is connected directly to the chip’s leads.
So the two must be compatible obviously see attachements. Back in those days, there were large manufacturing variations, so these chips were binned depending on their LEDs. What’s compatible with the 6N today? The H11L1 was mentioned, which I think might be easier to find -is it a direct replacement?
