Instructions for Use:

1. Power Supply Connection: Ensure the supply voltage (VCC) is within the specified range of 4.75V to 5.25V. Connect VCC and GND pins correctly.
2. Signal Levels: Input signals should be TTL-compatible levels. The device operates on standard TTL logic levels.
3. Pull-Up Resistors: Since the outputs are open collector, use appropriate pull-up resistors to define the logic level when the output is in the high impedance state.
4. Heat Management: If operating near maximum power dissipation, ensure adequate heat sinking or cooling methods are employed.
5. Handling Precautions: Handle the device with care to avoid damage from electrostatic discharge (ESD). Follow anti-static protocols during handling.
6. Installation: When installing on a PCB, ensure proper soldering techniques to maintain reliable connections and prevent overheating.
7. Testing: After installation, test the device under typical operating conditions to ensure correct functionality.

For detailed application notes and more specific information, refer to the manufacturer's datasheet.
