ISOM8111DFHR product

ISOM8111DFHR

Component

optocoupler emulatorDC inputopen collectorSOIC-4industrial isolation150% CTR

ISOM8111DFHR is a 4-pin DC-input optocoupler emulator with an open-collector transistor output and 150% to 230% CTR at 5 mA input current.

Best for

  • Isolated low-speed control signals
  • Switch-mode power-supply feedback
  • PLC and industrial I/O

Avoid if

  • A bidirectional input is required
  • The application needs a guaranteed logic-output driver without an external pull-up
  • Required isolation spacing exceeds the DFH package and PCB capability

Check before use

  • Minimum CTR over the intended current and temperature range
  • Collector current and pull-up resistor sizing
  • System creepage and clearance requirements
