TT ELECTRONICS / OPTEK TECHNOLOGY OPI1266

The OPI1266 is a 1-channel 5-pin High Voltage Isolator consists of a GaAIAs LED with a peak wavelength of 890nm, which is coupled with unique integrated circuit detector. Photons are collected in the detector by a photodiode and amplified by a high‐gain linear amplifier that drives a Schottky clamped open collector output transistor. The circuit is temperature, current and voltage compensated. Propagation delay times are matched within 500ns over the entire temperature range for timing purposes (ΔTP=tPHL‐tPLH). UL recognition is for 3500VRMS at 60Hz. This design produces maximum DC and AC current isolation between the input and output, while providing TTL/LSTTL circuit compatibility. It is suitable for data transmission for high voltage isolation, PC board power system isolation and office equipment.
