Instructions for Use

1. Power Supply: Ensure the supply voltage is within the specified range of 4.75V to 5.25V to avoid damage to the device.
2. Decoupling Capacitors: Place a 0.1 渭F decoupling capacitor close to the power pins to reduce noise and improve stability.
3. Signal Levels: Inputs should be driven by logic levels compatible with the LS family to ensure reliable operation.
4. Heat Dissipation: Although the LS family is designed for low power, ensure adequate ventilation if used in high-density applications.
5. Storage Conditions: Store in a dry environment away from direct sunlight and extreme temperatures.
6. Handling Precautions: Handle with care to prevent static damage; use anti-static precautions where necessary.
7. Mounting Orientation: Ensure correct orientation during PCB assembly to prevent short circuits or misconnections.

For detailed specifications and further instructions, refer to the manufacturer's datasheet.
