Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltages are with respect to GND.
2. Output may be shorted to supply.

NOTES:
3. The input irradiance E
e
is supplied by a GaAlAs infrared-emitting diode with
λ
p
= 880 nm.
4. Irradiance responsivity is characterized over the range V
O
= 0.05 to 3 V.
