  • TTL Compatible Output
  • 16KV Isolation
  • 2Mbd Transfer Rate
  • Creepage Path: 0.970” (24.64mm)
  • Air Path: 0.970” (24.64mm)
  • Low Propagation Delay Time The OPI1268 is a high voltage isolator with a digital output which is capable of high speed data transmission. This device is capable of DC and AC voltage isolation between the input and output circuitry while providing TTL signal integrity. The input of the OPI1268 consists of a high efficiency GaAlAs LED which is optically coupled to the output opti- cal 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 compen- sated. The result is a highly stable digital output in an open collector inverter configuration. Applications include:
  • High Voltage Isolation
  • PCBoard Power System Isolation
  • Industrial Equipment Power Isolation
  • Medical Equipment Power Isolation Product Photo Here
