Absolute Maximum Ratings, Tamb = 25 °C
Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. Functional operation of the device is
not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
Maximum Ratings for extended periods of time can adversely affect reliability.

1) f = 1.0 kHz, pulse width = 100 µs, load (RL) = 1.0 MΩ, 15 pF; measured at 90 % rated voltage (ton), 10 % rated voltage (toff). Actuation
speed depends upon the external ton and toff circuitry and the capacitance of the MOSFET.
Functional Description
Figure 1 outlines the IV characteristics of the illumi-
nated photodiode array (PDA). For operation at volt-
ages below VOC, the PDA acts as a nearly constant
current source. The actual region of operation
depends upon the load.
The amount of current applied to the LED (pins 1 and
2 or 3 and 4) determines the amount of light produced
for the PDA. For high temperature operation, more
LED current may be required.
