The maximum clock frequency for the SN74HC164PW is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the timing characteristics in the datasheet for specific frequency limits.
To ensure proper reset, connect the MR (Master Reset) pin to a pull-up resistor and a capacitor to VCC. This will ensure that the shift register is reset to a known state after power-on. Additionally, you can use an external reset signal to reset the shift register.
The maximum capacitance that can be driven by the SN74HC164PW outputs is 100 pF. Exceeding this limit may cause signal degradation and affect the overall performance of the shift register.
Yes, the SN74HC164PW can be used as a serial-to-parallel converter. By clocking in serial data and then latching the output, you can convert serial data to parallel data. However, note that the shift register is not designed for high-speed data conversion and may not be suitable for high-frequency applications.
To minimize clock skew and signal integrity issues, ensure that the clock signal is properly terminated and routed. Use a low-skew clock distribution network and consider using a clock buffer or repeater to maintain signal integrity. Additionally, use proper PCB layout techniques to minimize signal reflections and crosstalk.
