Description: The OPI1268 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 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 device produces DC and AC voltage isolation between the input and output circuitry while providing TTL signal integrity. 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 2Mbit/s tPHL-tPLH ≤ 500 ns Creepage path: 0.970” (24.64 mm) Air path: 0.970” (24.64 mm) UL recognized file No. E58730
