SN74HC165DRE4 datasheet by Texas Instruments

SN74HC165DRE4 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the SN74HC165DRE4?
  The maximum clock frequency for the SN74HC165DRE4 is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the datasheet for specific frequency limits at different operating conditions.
• Can I use the SN74HC165DRE4 with a 5V power supply?
  Yes, the SN74HC165DRE4 is compatible with 5V power supplies. However, it's recommended to ensure that the input voltage is within the recommended operating range of 4.5V to 5.5V to ensure reliable operation.
• How do I handle the output data format of the SN74HC165DRE4?
  The SN74HC165DRE4 outputs data in a serial format, with the most significant bit (MSB) first. You'll need to use a microcontroller or other logic circuitry to deserialize the data and convert it to a parallel format if needed.
• What is the propagation delay time for the SN74HC165DRE4?
  The propagation delay time for the SN74HC165DRE4 is typically around 10-15 ns, but it can vary depending on the operating voltage and temperature. Check the datasheet for specific propagation delay times at different operating conditions.
• Can I use the SN74HC165DRE4 in a high-temperature environment?
  The SN74HC165DRE4 is rated for operation up to 125°C, but it's recommended to derate the device for reliable operation at high temperatures. Check the datasheet for specific temperature ratings and derating guidelines.
