CD74HC257M Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC257M?
  The maximum frequency of operation for the CD74HC257M is typically 40 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the CD74HC257M is properly powered?
  The CD74HC257M requires a single power supply voltage (VCC) of 2.0 V to 6.0 V. Ensure that the power supply is stable and within the recommended operating range to ensure proper operation.
• What is the propagation delay time for the CD74HC257M?
  The propagation delay time (tpd) for the CD74HC257M is typically around 10 ns to 20 ns, depending on the operating frequency and voltage.
• Can I use the CD74HC257M in a 3.3 V or 5 V system?
  Yes, the CD74HC257M is compatible with both 3.3 V and 5 V systems, making it a versatile component for a wide range of applications.
• How do I handle the enable input (E) on the CD74HC257M?
  The enable input (E) is active-low, meaning that the device is enabled when E is low (logic 0) and disabled when E is high (logic 1). Ensure that the enable input is properly connected and controlled to avoid unintended behavior.
