Instructions for Use:

1. Supply Voltage (V_CC):

   • Ensure the supply voltage is within the operating range of 2.0 V to 5.5 V.
   • Use a stable power supply to avoid voltage fluctuations.

2. Input Voltages (V_IL, V_IH):

   • Inputs should be driven by voltages that meet the specified input low (V_IL) and high (V_IH) levels.
   • Ensure input signals do not exceed the supply voltage or go below ground.

3. Output Voltages (V_OL, V_OH):

   • The output low voltage (V_OL) should not exceed 0.4 V when sourcing 16 mA.
   • The output high voltage (V_OH) should be at least 2.4 V when sinking 4 mA.

4. Current Ratings (I_IN, I_OL, I_OH):

   • The input current (I_IN) should be within 卤1 渭A.
   • The output current (I_OL) can sink up to 16 mA.
   • The output current (I_OH) can source up to -4 mA.

5. Propagation Delay (t_pd):

   • The propagation delay time (t_pd) should be considered when designing timing-sensitive circuits.
   • Typical propagation delay is 3.5 ns, with a maximum of 7.0 ns.

6. Power Dissipation (P_D):

   • Ensure the total power dissipation does not exceed 100 mW to prevent overheating.
   • Use appropriate heat sinks or cooling methods if necessary.

7. Handling:

   • Handle the device with care to avoid static damage.
   • Store in a dry environment to prevent moisture-related issues.

8. Mounting:

   • Follow standard surface mount technology (SMT) guidelines for mounting.
   • Ensure proper soldering to maintain electrical connections and thermal performance.

9. Testing:

   • Test the device under specified conditions to ensure it meets the required performance parameters.
   • Use a multimeter or oscilloscope to verify input and output voltages and currents.

10. Compliance:

    • Ensure the device complies with relevant safety and regulatory standards for your application.
