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_CC ≤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_F > 80 mA will cause increased link t_PLH propagation delay time. This extended t_PLH time contributes to increased pulse
width distortion of the receiver output signal.
3. The LED drive circuit of Figure 11 is required for 1 MBd operation of the HFBR-25X2/25X4.
4. Optical flux, P (dBm) = 10 Log [P(µW)/1000 µW].
5. R_L is open.
