Instructions for Use:

1. Power Supply: Ensure that the supply voltage (V_DD) is within the specified range of 3 V to 15 V.
2. Input Levels: Apply high-level input voltages (V_IH) greater than or equal to 0.7 × V_DD and low-level input voltages (V_IL) less than or equal to 0.3 × V_DD.
3. Output Levels: The high-level output voltage (V_OH) should be at least V_DD - 0.5 V when sourcing 100 μA, and the low-level output voltage (V_OL) should be no more than 0.5 V when sinking 1.6 mA.
4. Current Limits: Do not exceed the maximum input current of ±1 μA and the maximum output current of -100 μA (source) and 1.6 mA (sink).
5. Propagation Delay: The typical propagation delay time (t_pd) is 25 ns at V_DD = 5 V and T_A = 25°C.
6. Temperature Ranges: Operate the device within the commercial temperature range of 0°C to 70°C and store it within the storage temperature range of -65°C to 150°C.
7. 3-State Operation: The HCF4028 has a 3-state enable input. When enabled, the outputs will reflect the decoded BCD input. When disabled, the outputs will be in a high-impedance state.
8. Pin Configuration: Refer to the datasheet for the specific pin configuration and connections.
