Instructions for Use:

1. Power Supply:

   • The HEF4044 can operate with a supply voltage (V_DD) ranging from 3V to 15V.
   • Ensure that the power supply is stable and within the specified range to avoid damage to the device.

2. Input Levels:

   • For reliable operation, input voltages should be kept within the specified limits.
   • Input low voltage (V_IL) should not exceed 0.8V when V_DD is 5V.
   • Input high voltage (V_IH) should be at least 2.0V when V_DD is 5V.

3. Output Levels:

   • Output low voltage (V_OL) should be below 0.6V when sourcing 0.4mA and V_DD is 5V.
   • Output high voltage (V_OH) should be above 2.7V when sinking -0.4mA and V_DD is 5V.

4. Leakage Current:

   • Both input and output leakage currents should be kept within ±1μA to ensure proper operation.

5. Propagation Delay:

   • The propagation delay time (t_pd) is typically between 12ns and 36ns under standard conditions (V_DD = 5V, f_L = 1kHz, C_L = 15pF).

6. Power Dissipation:

   • The maximum power dissipation per package is 100mW. Ensure adequate heat dissipation if operating near this limit.

7. Operating Temperature:

   • The device can operate over a temperature range from -40°C to 85°C. Ensure that the ambient temperature does not exceed these limits to prevent thermal damage.

8. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Use appropriate ESD protection measures during handling and installation.

9. Storage:

   • Store the device in a dry, cool place away from direct sunlight and sources of heat.

10. Soldering:

    • Use a soldering iron with a temperature not exceeding 300°C and complete the soldering process quickly to avoid thermal stress on the device.
