Help me with this date code

Hi!

I have some TI NE5534P opamps I bought years ago, with the following date code: 84AJL3M. The TI datasheet does not make it clear...🙄

On semiconductor also makes their version of the NE5534P. And on their datasheets, they specify the date code. Despite being in another format, the first two numbers MAY specify the YEAR of fabrication, but i'm not sure at all. This is why i ask here. ¿Is this opamp from TI (texas instruments), from the year 1984?

Thanks a lot!!
