74HC4017N,652 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the 74HC4017N?
  The maximum clock frequency is typically limited by the rise and fall times of the clock signal, but NXP recommends a maximum clock frequency of 10 MHz for the 74HC4017N.
• How do I ensure that the 74HC4017N is properly reset after power-on?
  To ensure proper reset, connect the MR (Master Reset) pin to VCC through a pull-up resistor (e.g., 1 kΩ) and add a capacitor (e.g., 100 nF) from MR to GND to filter out noise. This will ensure that the device is properly reset after power-on.
• What is the recommended operating voltage range for the 74HC4017N?
  The recommended operating voltage range for the 74HC4017N is 2 V to 6 V, with a typical operating voltage of 5 V.
• How do I handle the enable inputs (ENP and ENN) when not using them?
  When not using the enable inputs (ENP and ENN), tie them to VCC or GND, depending on the desired state. For example, if you want the device to always be enabled, tie ENP to VCC and ENN to GND.
• What is the maximum output current that the 74HC4017N can sink or source?
  The maximum output current that the 74HC4017N can sink or source is 25 mA per output pin, with a total device current limit of 100 mA.
