74HC4040DB,118 datasheet by NXP Semiconductors

74HC4040DB,118 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the 74HC4040DB,118?
  The maximum clock frequency for the 74HC4040DB,118 is 30 MHz, but it can be limited by the application and the quality of the clock signal.
• How do I ensure that the 74HC4040DB,118 is properly powered and decoupled?
  To ensure proper power and decoupling, use a 5V power supply with a minimum of 10uF decoupling capacitor between VCC and GND, and place the capacitor as close to the device as possible.
• What is the recommended operating temperature range for the 74HC4040DB,118?
  The recommended operating temperature range for the 74HC4040DB,118 is -40°C to +125°C, but it can be limited by the application and the quality of the device.
• How do I handle the asynchronous reset input (MR) of the 74HC4040DB,118?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure proper operation. A low level on MR resets the counter.
• What is the maximum output current that can be sourced or sunk by the 74HC4040DB,118?
  The maximum output current that can be sourced or sunk by the 74HC4040DB,118 is 25mA, but it's recommended to limit the output current to 10mA to ensure reliable operation.
