Logic Output Optoisolators

dual-channelhigh-speed optocouplerlogic-output optocoupler3750 Vrms isolation15 Mbit/sSOP-8

AT074L-CuH-S is a dual-channel, high-speed SOP-8 optocoupler for isolated logic signaling up to 15 Mbit/s. It supports 3.3 V or 5 V output-side supplies and specifies 3750 Vrms isolation.

Best for

  • Isolated PLC and industrial control signals
  • Servo-drive and motor-control logic isolation
  • Digital interfaces requiring two isolated channels

Avoid if

  • Applications requiring a documented lifecycle status
  • Designs that cannot provide approximately 12 mA to 18 mA LED drive current
  • Systems requiring isolation certification details not stated in this datasheet

Check before use

  • Confirm output polarity for each channel
  • Place 0.1 µF output-side supply decoupling near the device
  • Verify PCB creepage and clearance for the system isolation voltage
