CD74HC257M Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the CD74HC257M is typically 40 MHz, but it can vary depending on the specific application and operating conditions.
  • 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.
  • The propagation delay time (tpd) for the CD74HC257M is typically around 10 ns to 20 ns, depending on the operating frequency and voltage.
  • 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.
  • 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.
