Instructions for Use:

1. Supply Voltage (Vcc):

   • Ensure the supply voltage is within the range of 4.5V to 5.5V to avoid damage to the device.

2. Output Voltage Levels:

   • When the output is high (VOH), it should be at least 2.4V under a load current of -0.4 mA.
   • When the output is low (VOL), it should not exceed 0.4V under a load current of 16 mA.

3. Input Voltage Levels:

   • For the input to be recognized as high (VIH), the voltage must be at least 2V.
   • For the input to be recognized as low (VIL), the voltage must not exceed 0.8V.

4. Propagation Delay Time (tpd):

   • The propagation delay time is the time it takes for a change in input to affect the output. At 5V and 25°C, this time is typically 12 nanoseconds.

5. Power Dissipation (PD):

   • The maximum power dissipation should not exceed 100 mW to prevent overheating and potential damage.

6. Operating Temperature (TA):

   • The device is designed to operate within a temperature range of -40°C to 85°C. Ensure the ambient temperature does not exceed these limits.

7. Storage Temperature (Tstg):

   • When storing the device, ensure the temperature remains between -65°C and 150°C to maintain its integrity.

8. Handling Precautions:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Ensure all connections are secure and properly soldered to prevent intermittent operation.

9. Testing and Troubleshooting:

   • Use a multimeter to verify the supply voltage and output levels.
   • Check for any short circuits or open circuits in the connections.
   • If the device fails to operate correctly, refer to the datasheet for additional troubleshooting tips.
