The 54LS51FMQB is an AND-OR-INVERT gate from the LS series.
That is typical for through-hole or ceramic flat-pack devices in the 54LS family. Plan for manual or tube-fed insertion; it will not feed through a pick-and-place machine without a carrier.
It performs the logic function (A·B)+(C·D) inverted — a standard combinatorial logic building block.
The 4030BDM is a peer part in the same functional class — a quad XOR gate — but it is a different logic function (XOR vs AND-OR-INVERT). For a direct AND-OR-INVERT replacement, stick with the 54LS51FMQB or check the 54LS family for pin-compatible variants.
