LM34: LM3490IM5 Marking on the bottom

Part Number: LM34

Hello, dear colleagues.I'm sorry, I couldn't specify the correct part number in the form, it is written that such a part number was not found. So I specified a similar one. Please help me understand the markings on the bottom of the LM3490IM5. The lower part is marked with the letters "XRA" which means this marking. Can I use it to determine the component's production date?
