CD74HC21E Frequently Asked Questions (FAQs)

  • The CD74HC21E can operate at frequencies up to 25 MHz.
  • The CD74HC21E requires a power supply voltage (VCC) of 2.0 V to 6.0 V, and it is recommended to decouple the power supply with a 0.1 μF capacitor.
  • The maximum input voltage that the CD74HC21E can handle is 6.0 V, and exceeding this voltage may cause damage to the device.
  • The output of the CD74HC21E is an open-drain output, which means it can sink current but cannot source current. Therefore, an external pull-up resistor is required to pull the output high.
  • The propagation delay of the CD74HC21E is typically around 10 ns, but it can vary depending on the operating frequency and load capacitance.
