74HC4040N,652 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the 74HC4040N?
  The maximum clock frequency for the 74HC4040N is 25 MHz, but it can be operated at higher frequencies with reduced supply voltage and/or lower temperatures.
• How do I ensure that the 74HC4040N is properly powered and decoupled?
  To ensure proper power and decoupling, use a 0.1 μF ceramic capacitor between VCC and GND, and a 10 μF electrolytic capacitor between VCC and GND, with a maximum distance of 10 mm from the device.
• What is the recommended operating temperature range for the 74HC4040N?
  The recommended operating temperature range for the 74HC4040N is -40°C to +125°C, but it can be operated at temperatures up to 150°C with reduced reliability.
• How do I handle the asynchronous reset input (MR) during power-up?
  During power-up, the asynchronous reset input (MR) should be held low for at least 10 ns to ensure that the device is properly reset. After power-up, MR can be released to allow normal operation.
• What is the maximum output current that can be sourced or sunk by the 74HC4040N?
  The maximum output current that can be sourced or sunk by the 74HC4040N is 25 mA per output pin, with a total current limit of 100 mA for all output pins combined.
