Instructions for Use

1. Supply Voltage:

   • Ensure the supply voltage (V_CC) is within the range of 2.0V to 6.0V to avoid damage to the device.

2. Input Levels:

   • Inputs should be driven to either a low level (V_IL ≤ 0.8V) or a high level (V_IH ≥ 2.0V) to ensure proper operation.

3. Output Levels:

   • When the output is low, it will typically be around 0.1V (V_OL). When high, it will be at least 2.4V (V_OH).

4. Leakage Current:

   • Both input and output leakage currents should be kept below ±1μA to prevent unwanted behavior.

5. Propagation Delay:

   • The typical propagation delay time (t_pd) is 6ns, with a maximum of 18ns. This is important for timing considerations in your circuit.

6. Power Dissipation:

   • The device can dissipate up to 100mW of power. Ensure adequate heat dissipation if operating near this limit.

7. Temperature Ranges:

   • The operating temperature range is from -40°C to 85°C. The storage temperature range is from -65°C to 150°C.

8. Handling:

   • Handle the device with care to avoid static discharge, which can damage sensitive components. Use appropriate ESD protection measures.

9. Mounting:

   • Follow recommended soldering profiles and mounting guidelines to ensure reliable connections and prevent thermal stress on the device.

10. Testing:

    • After assembly, perform functional tests to verify that the device is operating correctly according to the specified parameters.
