Instructions for Use:

1. Supply Voltage (V_CC):

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

2. Input Voltage (V_I):

   • The input voltage should not exceed V_CC + 0.5 V or go below -0.5 V to prevent damage to the input pins.

3. Output Voltage (V_O):

   • For V_CC = 5 V, the output voltage when driving a load with I_OL = 16 mA should be no more than 0.3 V.
   • When driving a load with I_OH = -4 mA, the output voltage should be at least V_CC - 0.3 V.

4. Input Leakage Current (I_IL):

   • The maximum input leakage current is ±1.0 μA. Ensure that any pull-up or pull-down resistors are sized appropriately to account for this leakage.

5. Output Current (I_OL, I_OH):

   • The device can sink up to 16 mA and source up to -4 mA. Design your circuit to ensure these limits are not exceeded.

6. Propagation Delay Time (t_pd):

   • The typical propagation delay time is 5.0 ns. This is important for timing considerations in digital circuits.

7. Power Dissipation (P_D):

   • The maximum power dissipation is 340 mW. Ensure adequate heat sinking or cooling if the device is expected to operate near this limit.

8. Operating Temperature Range (T_A):

   • The device can operate in ambient temperatures ranging from -40°C to 85°C. Ensure the environment does not exceed these limits.

9. Storage Temperature Range (T_STG):

   • Store the device in temperatures ranging from -65°C to 150°C to prevent damage during storage.

10. Handling:

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

11. Mounting:

    • Follow standard surface mount technology (SMT) guidelines for mounting the device on a PCB. Ensure proper soldering and alignment to prevent mechanical stress.
