Description: The OPI1266 is a high voltage isolator that consists of a GaAIAs LED with a peak wavelength of 890 nm, which is coupled with a 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 a nd voltage compensated. Propagation delay times are matched within 500 nanoseconds over the entire temperature range for timing purposes (Δ TP = tPHL-tPLH). *UL recognition is for 15kV dc. This design produces maximum DC and AC current isolation between the input and output, while providing TTL/LSTTL circuit compatibility. Applications: Data transmission for High voltage isolation PCBoard power system isolation Industrial equipment power isolation Medical equipment power isolation Office equipment Features: TTL compatible output 16 kV dc isolation 500 kbits/s transfer rate tPHL-tPLH ≤ 500 ns Creepage path: 0.970” (24.64 mm) Air path: 0.970” (24.64 mm) UL recognized file No. E58730*
