OPI1268S High-Voltage, High-Speed Opto-Isolator

Optek / TT Electronics OPI1268S High-Voltage, High-Speed Opto-Isolator offers a digital output that is capable of high speed data transmission. The input of this opto-isolator consists of a high-efficiency GaAlAs LED with a peak wavelength of 850nm, which is optically coupled to the output optical IC. A photodiode in the output IC detects the incoming modulated light and converts it to a proportionate current. This current is fed into a high gain linear amplifier which is temperature, current, and voltage compensated. The result is a highly stable digital output with an open collector inverter configuration. This Optek High Voltage, High Speed Opto-Isolator produces DC and AC voltage isolation between the input and output circuitry while providing TTL signal integrity.
