74ls02 is a member of the 74XXYY IC series. 74ls02 is a 14 pin ic with four NOR gates each gate has two inputs hence it called Quad 2 input nor gate. The IC is functional with all other 74LS logic family and it can be operating with any microcontroller or IC due to its low output compatibility.
74ls02 nor gate also comes up with internal protection from discharge using clamp diodes, which keep it protected from any internal voltage leakage activity.
