Average value (duty ratio 50 %) measured by using a plastic fiber of φ1 mm. SI-POF and NA=0.5 (GH4001 made by Mitsubishi Rayon). Measured with the recommended driver circuit shown below. (Measurement conditions: Vcc=4.5 to 5.5 V, R1=750 Ω , R2=2.2 k Ω , R3=22 Ω , C1=35 pF) Note:

  • A bypass capacitor (0.1 µF) and another capacitor (4.7 µF) are connected between Vcc and GND at a position within 3 mm from the lead.
  • The center of the optical fiber is aligned with the center of the lens on the package. The distance between the fiber end and the lens is 0.1 mm. Vcc Icc SIGNAL INPUT 1 14 74ACT08 4.7 /K6D F 0.1 /K6D FR 2 L8045 KLEDC0018EB
