Description: The OPI1268S is a high voltage isolator with a digital output that is capable of high speed data transmission. The input of the OPI1268 consists of a high -efficiency GaAlAs LED with a peak wavelength of 850 nm, which is optically coupled to the output optical IC. A photologic device 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 device produces DC and AC voltage isolation between the input and output circuitry while providing TTL signal integrity. Applications: Transportation Systems PC Board Power Systems Hybrid Vehicle Systems Medical Systems Control Systems Features: 20kV dc Isolation 2 Mbit/s transfer rate tPHL-tPLH ≤ 50 ns typical Creepage path: 24 mm TTL Compatible 6 Axis / 10GRMS load rating Certifications: UL File E58730 Vde File 40031798 EN 60079-0:2012/A11:2013 EN60079-11:2012 (IEC 60079-11:2011 Edition 6) IP65 Rated ATEX Certification Exia IIc Ga
