The recommended operating voltage range for the CD74HC40105M is 2V to 6V, with a typical voltage of 5V.
Unused inputs of the CD74HC40105M should be tied to VCC or GND to prevent floating inputs, which can cause unpredictable behavior.
The maximum clock frequency that the CD74HC40105M can handle is 25 MHz, but this can vary depending on the operating voltage and load capacitance.
Yes, the CD74HC40105M can be used in a 3.3V system, but the output voltage will be limited to 3.3V, and the device may not be able to drive heavy loads.
To ensure proper power-up and initialization, the CD74HC40105M should be powered up slowly (dv/dt < 10V/μs) and the clock input should be low during power-up.
