74LS02 Quad Two Input NOR Gate – Datasheet

74LS02 is a member of the 74XXYY IC series. The 74LS02 is a TTL (Transistor to Transistor Logic) which uses low power Shottky transistors to reduce the stored charge and get higher switching speeds than with conventional bipolar transistors. 74LS02 is a 14 pin IC that has four NOR gates each NOR gate has two inputs & one output.

NOR Gate ?

In Digital Electronics NOR Gate is the logic gate that produces an output High (1) if one Or both the inputs to the gate are Low (0). NOR is the result of the negation of the OR operator.
