i am using 6N137 high speed optocoupler but problem is op is inverted.

so i required high speed (frq >= 100KHz) optocoupler with non-inverted op.

or how can i get non inverted op using 6N137 ?

Just change the drive circuit:

  • via software: invert the logical level at PB9, e.g. by programming of the driving mcu
  • via hardware: connect pin 3 to primary GND and drive the optocoupler at pin 2, alternatively invert the signal using a transistor with pull-up at the input or output of the optocoupler
