Optocoupler Products Specifications

Definitions

  1. CTR (current transfer ratio): Ratio of the collector to the diode forward current IC/IF.
  2. IF: Current flowing through a diode from anode to cathode.
  3. BVCEO: Collector to emitter breakdown voltage with the collector open.
  4. BVCBO: Collector to base breakdown voltage with the emitter open.
  5. BVECO: Emitter to collector breakdown voltage with the base open.
  6. VCE(sat): Collector to emitter saturation voltage.
  7. tON/tOFF:Turn-on switching time; turn-off switching time.
  8. VISO: Isolation voltage rating in ACRMS (1 second rating).
  9. Agency Approvals: Safety agency approvals that correspond to the part number.
  10. IFT: Diode forward current (IF) required to cause the output to change states.
  11. VOL: Logic low output voltage.
  12. VCC: Operating supply voltage.
  13. CMH;CML: Common mode transient immunity at logic high level output; common mode transient immunity at logic low level output.
  14. IOH: Logic high output current.
  15. tPLH/tPHL: Propagation delay time to logic high output; propagation delay time to logic low output.
  16. ICCL: Current drawn from the supply at logic low output.
  17. VTM: On-state voltage.
  18. VDM: Blocking voltage.
  19. IDM: Off-state current.
