The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 2:
ESD testing conforms to MIL-STD-883, Method 3015.

The specified limits represent the “worst case” value for the parameter. Since these values normally occur at the temperature extremes, additional
noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are cho-
sen to guarantee operation under “worst case” conditions.

Output-to-Output Skew is defined as the absolute value of the difference between the actual propagation delay for any outputs within the same pack-
aged device. The specifications apply to any outputs switching in the same direction either HIGH-to-LOW (t

白光LED光衰原因之荧光粉性能的衰退 到目前，白光 LED、尤其是小功率白光 LED 的发光性能快速衰退已越来越为人们所认识。其实，盲目地夸大宣传，只能将 LED 行业引向歧途，不正视白光 LED 存在的问题，只能延缓白光 LED 应用的发展。只有正视问题、研究问题、尽早解决问题，白光 LED 才能健康、快速发展。 白光 LED 当前面临的一个主要问题就寿命问题。由于白光 LED 的价格尚很...[详细]
