Notes:
1. 1.6 mm below seating plane.
2. The signal output is an emitter follower, which does not reject noise in the power supply. The power supply must be filtered as in
Figure 1.
3. Typical data are at 25

C and V
CC
= +5 Vdc.
4. Pin 1 should be ac coupled to a load
510
with load capacitance less than 5 pF.
5. Measured with a 3 pole Bessel filter with a 75 MHz, -3dB bandwidth.
6. The maximum Peak Input Optical Power is the level at which the Pulse Width Distortion is guaranteed to be less than the PWD listed
under Test Condition. P

is given for PWD = 5 ns for designing links at
50 MBd operation, and also for PWD = 2 ns for
designing links up to 125 MBd (for both POF and HCS input conditions).
7. 10 ns pulse width, 50% duty cycle, at the 50% amplitude point of the waveform.

9. Pins 5 and 8 are primarily for mounting and retaining purposes, but are electrically connected. It is recommended that these pins be
connected to ground to reduce coupling of electrical noise.
10. If there is no input optical power to the receiver (no transmitted signal) electrical noise can result in false triggering of the receiver.
In typical applications, data encoding and error detection prevent random triggering from being interpreted as valid data. Refer to
Application Note 1066 for design guidelines.
