CD74HC175E datasheet by Texas Instruments

CD74HC175E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for CD74HC175E?
  The maximum frequency of operation for CD74HC175E is 25 MHz, but it can vary depending on the operating voltage and load capacitance.
• How do I ensure that the outputs are not floating during power-up or power-down?
  To ensure that the outputs are not floating during power-up or power-down, you can use pull-up or pull-down resistors on the output lines. Additionally, you can use a power-on reset circuit to initialize the device.
• Can I use CD74HC175E in a 5V system?
  Yes, CD74HC175E can operate in a 5V system, but you need to ensure that the input voltage is within the recommended operating range of 2V to 6V. Additionally, you may need to adjust the output voltage levels to match the 5V system requirements.
• How do I handle the asynchronous reset input (MR) during normal operation?
  During normal operation, the asynchronous reset input (MR) should be tied to VCC or a logic high level to prevent accidental resets. If you need to use the reset function, ensure that the MR input is driven by a logic signal that meets the input voltage requirements.
• What is the recommended operating temperature range for CD74HC175E?
  The recommended operating temperature range for CD74HC175E is -40°C to 85°C. However, the device can operate up to 125°C with reduced performance and reliability.
