OPI126 - OPTICALLY COUPLED ISOLATOR

Download the OPI126 datasheet PDF. This datasheet also covers the OPI125 variant, as both devices belong to the same optically coupled isolator family and are provided as variant models within a single manufacturer datasheet.

General Description

Each OPI125, OPI126, and OPI128 consists of an optically coupled isolator with a gallium arsenide infrared emitting diode coupled to a monolithic integrated circuit.

This circuit incorporates a photodiode, a linear amplifier and a Schmitt trigger on a single silicon chip.

Key Features

  • Multiple output options.
  • 15 kV dc input-to-output isolation voltage.
  • Direct TTL/STTL interface.
  • High noise immunity.
  • Data rates to 250 KBit/s.
  • Hermetically sealed.
  • TX-TXV process available.
  • UL File No. E 58730.
