PHOTOCOUPLER
6N137 series
1. DESCRIPTION
The 6N137 consists of a high efficient AlGaAs Light Emitting Diode and a high speed optical detector. This design provides
excellent AC and DC isolation between the input and output sides of the Optocoupler. The output of the optical detector features an
open collector Schottky clamped transistor. The enable function allows the optical detector to be strobed. A guaranteed common mode
transient immunity is up to 10kV/μs at 3.3V.
The Optocoupler operational parameters are guaranteed over the temperature range from -40
