Instructions for Use:

1. Power Supply Connection:

   • Connect the positive supply voltage (Vcc) to pin 14.
   • Connect the ground (GND) to pin 7.

2. Signal Connections:

   • Connect input signals to the appropriate input pins as per the logic function required.
   • Ensure all unused inputs are connected to a defined logic level (typically Vcc or GND).

3. Output Handling:

   • Since the outputs are open collector, external pull-up resistors are required to achieve proper logic levels.
   • Choose a pull-up resistor value that balances speed and power consumption, typically between 1k惟 and 10k惟.

4. Heat Dissipation:

   • For applications where the device may operate near its maximum temperature limits, ensure adequate heat sinking or cooling.

5. Handling Precautions:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).
   • Follow standard anti-static precautions during assembly and handling.

6. Storage Conditions:

   • Store in a dry, cool environment away from direct sunlight and sources of heat.

7. Compliance:

   • Ensure compliance with relevant standards and regulations for electronic components in your application.
