Table 1. Absolute Maximum Ratings
Note: Stresses in excess of those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions in excess of those indicated in the operational sec-
tions of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reli-
ability.
Table 2. Static Electrical Characteristics
(Tamb within operating range, VDD = 4.75V to 13.2V, VSS = 0V, unless otherwise specified)
Note: 1. Output matching is calculated as the percent variation from I MAX + IMIN/2.
2. With a fixed resistor on the brightness input some variation in brightness will occur from one device to another.
3. Absolute maximum for each output should be limited to 40mA.
4. The VO voltage should be regulated by the user.
