Detail/Procurement Specification Vs Manufacturer Datasheets.

the datasheet is not always under strict configuration control, and the information included can be changed without notice or even be outdated. This is, the datasheet is always under manufacturer control. This also implies that some parameter information that may be critical for a specific customer application may not be shown in the datasheet if the manufacturer does not consider it typically important. Furthermore, it may happen that this parameter has not even been measured ever.
