The 74LS02 DIP-14 Inverter and Gate Integrated Circuit is a digital logic integrated circuit belonging to the TTL (Transistor-Transistor Logic) family, containing four two-input NOR gates. Its DIP-14 package allows for easy use on breadboards or circuit boards.
A NOR gate is one of the “universal gates” of digital circuits — just like NAND, it produces a LOW (0) output only for certain input combinations. When all inputs are 0, its output is 1; returns 0 in all other cases.
