74HC165D Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the 74HC165D?
  The maximum clock frequency for the 74HC165D is 25 MHz.
• Can I use the 74HC165D as a parallel-in, serial-out shift register?
  Yes, the 74HC165D 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 when the parallel load input (PL) is low.
• How do I reset the 74HC165D?
  The 74HC165D can be reset by applying a low signal to the reset input (R) for at least 10 ns. This resets the shift register to its initial state.
• What is the propagation delay time for the 74HC165D?
  The propagation delay time for the 74HC165D is typically 10 ns from clock to output (tCLQ) and 15 ns from parallel load to output (tPLQ).
• Can I use the 74HC165D in a 5V system?
  Yes, the 74HC165D is compatible with 5V systems. It operates from a supply voltage range of 2V to 6V.
