The recommended operating voltage range for the SN54HC4024J is 2V to 6V, with a typical voltage of 5V.
When the input pins are not in use, they should be tied to a valid logic level (either VCC or GND) to prevent them from floating and causing unwanted behavior.
The maximum clock frequency that the SN54HC4024J can handle is 25 MHz, but this can vary depending on the operating voltage and other factors.
Yes, the SN54HC4024J can be used in a 3.3V system, but the input and output voltage levels may need to be adjusted accordingly.
To ensure that the SN54HC4024J is properly powered, a decoupling capacitor (typically 0.1uF) should be placed close to the VCC pin, and the power supply should be able to provide sufficient current to drive the device.
