6N137
High CMR, High Speed TTL Compatible Optocouplers
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. The internal
shield ensures high common mode transient
immunity. A guaranteed common mode
transient immunity is up to 10,000V/µs.
The Optocoupler operational parameters
are guaranteed over the temperature range
from -40
