TL084: Date code on thr front of the IC

Part Number:TL084

I am interested in knowing the lot and manufacturing date of some TL084CN chips I have just bought.

On the front of the chip above the TL084CN identification it is written 45A720M and on the backside it is witten in side one of the two circles the chip has it is written 0H90.

Are these markings enough to identify the lot and teh manufacturing date of the chips.

Thanks in advance,

Atanasio

P.S.: The shop where I acquired chips made their acquisition on May 2015
