Notes:
1. 1.6 mm below seating plane.
2. It is essential that a bypass capacitor 0.01 µF be connected from pin 2 to pin 3 of the receiver. Total lead length between both ends of the capacitor
and the pins should not exceed 20 mm.
Receiver Electrical/Optical Characteristics 0°C to 70°C, 4.75 V ≤V ≤5.25 V unless otherwise specified.

Notes:
1. Measured at the end of the fiber optic cable with large area detector.
2. Pulsed LED operation at I > 80 mA will cause increased link t
propagation delay time. This extended t time contributes to increased pulse
