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 ≤ VCC ≤ 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 IF > 80 mA will cause increased link tPLH propagation delay time. This extended tPLH 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. RL is open.
