Instructions for Use:

1. Power Supply Connection: Connect VDD to the positive supply and VSS to ground. Ensure the supply voltage is within the specified range of 3V to 15V.
2. Input Signals: Apply input signals to the designated input pins. The logic levels should be within the defined VIH and VIL ranges relative to VDD.
3. Output Handling: Since the outputs are open collector, external pull-up resistors are required for proper operation. Choose a resistor value that provides sufficient current for your application while ensuring the output voltage remains within the VOH and VOL specifications.
4. Temperature Considerations: Operate the device within the temperature range of -40掳C to +85掳C to ensure reliable performance.
5. Handling Precautions: Follow standard ESD (Electrostatic Discharge) precautions when handling the component to avoid damage.
6. Mounting: Ensure proper mounting orientation and secure connections to prevent mechanical stress on the package leads.
