The maximum clock frequency for the CD74HC164M is 25 MHz.
Yes, the CD74HC164M can operate with a power supply voltage range of 2V to 6V, including 5V.
The CD74HC164M has a asynchronous reset input (SRCLR) that can be used to reset the shift register. When SRCLR is low, the shift register is reset.
Yes, the CD74HC164M can be used as a serial-to-parallel converter. The shift register can be loaded serially and then the data can be output in parallel.
The propagation delay of the CD74HC164M is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
