Note:
1. Derate linearly 2.22mW / ºC above 25ºC
2. Derate linearly 4.44mW / ºC above 25ºC
3. Derate linearly 6.66mW / ºC above 25ºC
4. The optical switches are terminated with 24 inches
of 26 A.W.G.,UL 1492 wire on each terminal.
Insulation colors and function are as follows:
Red-Anode, Black-Cathode, White-Vcc, Blue-Output,
Green-Ground
5. Normal application would be used with light source blocked,
simulated by I
F
=0mA
6. All parameters tested using pulse techniques.
7. Minimum supply voltage is 4.5 VDC
