Even unloaded outputs aren’t consistent, unless you use a pullup resistor. I looked at their data sheet and found out they are similar regardless their pin out, may be i’m missing some the big picture ao that’s why i’m asking precisely if they do function the same, thanks for any info that helps.

NO This mainly due to Vih min threshold can exceed Voh guaranteed if driven by another 74LSxx part and differences in the Disable function.

Operation of the OE input does not affect the state of the flip-flops. THe reason the part numbers changed root number xxx is due to the functional differences in output enable to tri-state for the HC version. The device inputs are compatible with standard CMOS outputspackage dimensions section on page 3 of this data sheet.
