The SN74LS02NS is an Integrated Circuit (IC) component that belongs to the LS family of TTL (Transistor-Transistor Logic) logic gates. It is a Quadruple 2-input Positive-NOR gate designed to perform logical NOR operations. Here is an overview of its key features:
1. Package: The SN74LS02NS is available in a small-outline integrated circuit (SOIC) package. This package is compact and ideal for use in applications with limited space.
2. Circuit Configuration: This IC contains four individual 2-input NOR gates, making it a quad gate configuration. It offers a compact solution by providing multiple NOR gates in a single chip.
3. Input Characteristics: The SN74LS02NS has two inputs per gate, labeled A and B. These inputs can accept standard TTL logic levels, characterized by low (0V to 0.8V) and high (2V to 5V) voltage ranges.
4. Output Characteristics: Each NOR gate in the IC provides a single output labeled Y. The output can sink or source current up to 8 mA, allowing it to drive directly into standard TTL loads.
5. Propagation Delay Time: The SN74LS02NS has a propagation delay time of a few nanoseconds. This speed is critical in applications that require fast response times.
6. Power Supply: It operates with a power supply voltage (Vcc) ranging from 4.75V to 5
