Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 3.0 V to 18.0 V.
   • Connect V_CC to the positive supply and GND to the ground.

2. Input Signals:

   • For a valid high input (V_IH), the voltage must be at least 6.0 V.
   • For a valid low input (V_IL), the voltage must be no more than 1.5 V.

3. Output Signals:

   • The output high voltage (V_OH) will be around 13.5 V when the output is high.
   • The output low voltage (V_OL) will be around 0.25 V when the output is low.

4. Propagation Delay:

   • The propagation delay time (t_pd) is typically 300 ns at V_CC = 15 V and f = 10 kHz.

5. Temperature Considerations:

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

6. Power Dissipation:

   • The maximum power dissipation (P_D) is 150 mW.

7. Handling:

   • Handle the HEF4528BT with care to avoid static discharge, which can damage the device.
   • Follow standard ESD (Electrostatic Discharge) precautions during handling and installation.

8. Testing:

   • Before using the device in a circuit, test it under the specified conditions to ensure it meets the required performance parameters.

9. Layout and PCB Design:

   • Ensure proper PCB layout to minimize noise and interference. Use short leads and decoupling capacitors close to the power pins if necessary.

10. Applications:

    • The HEF4528BT is suitable for use in various digital circuits, including counters, timers, and other logic applications.
