SN74HC165D datasheet by Texas Instruments

SN74HC165D Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HC165D can handle?
  The maximum clock frequency of the SN74HC165D is 25 MHz.
• Can I use the SN74HC165D as a parallel-in, serial-out shift register?
  Yes, the SN74HC165D can be used as a parallel-in, serial-out shift register. The parallel data is loaded into the shift register on the rising edge of the clock signal.
• How do I reset the shift register?
  The shift register can be reset by applying a low signal to the CLEAR (CLR) input. This resets the shift register to an all-zero state.
• What is the propagation delay of the SN74HC165D?
  The propagation delay of the SN74HC165D is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
• Can I use the SN74HC165D in a 5V system?
  Yes, the SN74HC165D is compatible with 5V systems. However, it can also operate at lower voltages down to 2V, making it suitable for use in a wide range of applications.
