Notes:

1. 2.0 mm from where leads enter case.

2. 8 mA load (5 x 1.6 mA), RL = 560 Ω.

3. Typical data at TA = 25°C, VCC = 5.0 Vdc.

4. D is the effective diameter of the detector image on the plane of the fiber face. The numerical value is the product of the actual

detector diameter and the lens magnification.

5. Measured at the end of 100/140 µm fiber optic cable with large area detector.

6. Propagation delay through the system is the result of several sequentially-occurring phenomena. Consequently it is a combination

of data-rate-limiting effects and of transmission-time effects. Because of this, the data-rate limit of the system must be described in

terms of time differentials between delays imposed on falling and rising edges.

7. As the cable length is increased, the propagation delays increase at 5 ns per meter of length. Data rate, as limited by pulse width

distortion, is not affected by increasing cable length if the optical power level at the receiver is maintained.

CAUTION: The small junction sizes inherent to the design of these components increase the components’

susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be

taken in handling and assembly of these components to prevent damage and/or degradation which may be

induced by ESD.
