Well tried finding the relevant datasheets but, no joy - the general SGS sheets on 74LS series say the suffix should be B for a DIP - I wonder if it is a different manufacturer - maybe a CMOS part or an original 74365 non schotty even. TI parts had an A after them. I am going with a relabelled chip of unknown exact design due to your observation on the BATCH number...
