Instructions for Use:

1. Pin Configuration: Ensure the correct orientation of the SN74LS32 by aligning the notches or marks on the IC with the corresponding indicators on the PCB.
2. Power Supply: Connect the power supply pins (Vcc and GND) correctly. The typical operating voltage is 5V.
3. Signal Connections: Connect input signals to the designated input pins. Each OR gate has two inputs.
4. Grounding: Ensure a good ground connection to avoid noise and ensure stable operation.
5. Decoupling Capacitors: Place decoupling capacitors close to the power supply pins to reduce noise and transient effects.
6. Handling Precautions: Handle the IC carefully to avoid damage from electrostatic discharge (ESD). Use appropriate ESD protection measures.
7. Heat Management: Although designed for low power, ensure adequate ventilation or heat dissipation if used in high-density circuits or enclosed spaces.
