CD74HCT4520E Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the CD74HCT4520E is 30 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure reliable operation in high-temperature environments, it is recommended to follow proper thermal management practices, such as providing adequate heat sinking and airflow, and ensuring that the device is operated within its specified temperature range (-40°C to 125°C).
  • The recommended power-on sequence for the CD74HCT4520E is to apply power to the VCC pin before applying any input signals, and to ensure that the power supply is stable and within the specified voltage range (2V to 6V) before applying any inputs.
  • Unused inputs on the CD74HCT4520E should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure reliable operation.
  • The maximum current that can be sourced or sunk by the CD74HCT4520E is 25 mA per output pin, but it is recommended to limit the current to 10 mA or less to ensure reliable operation and prevent overheating.
