6N135, 6N136
Single Channel, High Speed Optocouplers
Description
The 6N135/6 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.
Connection for the bias of the photodiode
improves the speed that of a conventional
phototransistor coupler by reducing the
base-collector capacitances. The internal
shield ensures high common mode transient
immunity. A guaranteed common mode
transient immunity is up to 1KV/μsec.
