The maximum clock frequency for the CD74HC164E is 25 MHz.
Yes, the CD74HC164E can operate with a power supply voltage range of 2V to 6V, including 5V.
The CD74HC164E has an asynchronous reset input (SRCLR) that can be used to reset the shift register. When SRCLR is low, the shift register is reset.
Yes, the CD74HC164E 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 from the Q0-Q7 outputs.
The propagation delay time for the CD74HC164E is typically around 10-15 ns, depending on the operating conditions.
