LM4040-N-Q1: Operating temp range of 4.096V precision voltage reference

Part Number: LM4040-N-Q1

Tool/software:

what is the operating temperature range for the LM4040A41IDBZR.  On Mouser, it states -40 to 125 C, but the datasheet does not match that information.  Also the datasheet says there is an extended temp range of -40 to 125 C but does not tell what the part number is for it.  and, I have found 3 different datasheets for the same part.  I have no idea what is what.  please help
