SN74HC165QPWRG4Q1 datasheet by Texas Instruments

SN74HC165QPWRG4Q1 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the SN74HC165?
  The maximum clock frequency for the SN74HC165 is 25 MHz, but it can vary depending on the operating voltage and temperature.
• How do I ensure data integrity when shifting data in and out of the SN74HC165?
  To ensure data integrity, it's essential to synchronize the clock signal with the data signal, and use a suitable clock frequency to avoid metastability issues.
• Can I use the SN74HC165 as a serial-to-parallel converter?
  Yes, the SN74HC165 can be used as a serial-to-parallel converter by connecting the serial input to the data input (D) and the parallel output to the Q0-Q7 pins.
• What is the purpose of the /OE (output enable) pin?
  The /OE pin is used to enable or disable the output buffers. When /OE is low, the outputs are enabled, and when /OE is high, the outputs are in a high-impedance state.
• How do I reset the SN74HC165?
  The SN74HC165 can be reset by applying a low signal to the /SR (serial reset) pin. This resets the shift register to its initial state.
