What is the difference between a H11L1 and H11L1M opto coupler? (I want to use it for MIDI).
If I check the data sheets, I see some different values, but for me it is unclear to know if these will affect the usage for MIDI ...
I want to buy it actually from AliExpress (either the H11L1 or H11L1M), which do not specify a datasheet, but I assume I can consider all H11L1's having the same specs and all H11L1M's (?)
(also I always thought the H would be the manufacturer's 'code'), but H11L1 seems to be from Motorola and H11L1M from Fairchild).
