It means the part can fan out to ten standard LSTTL loads or drive a heavily loaded 3.3 V bus with controlled edge rates. If your BOM currently uses a 74LVC244A in a smaller package and you need the wider 20-SOIC for board layout or thermal reasons, this part drops in electrically with the same drive strength.
