CD4521BE Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the CD4521BE is 4.5V to 15.5V, although the device can operate with a minimum voltage of 3V.
  • To ensure proper power-on and power-off, it's recommended to use a capacitor (e.g., 0.1uF) between VCC and GND, and to sequence the power supply voltage (VCC) and the clock signal (CLK) to prevent unwanted oscillations.
  • The CD4521BE can handle clock frequencies up to 10 MHz, but the maximum frequency may vary depending on the specific application and operating conditions.
  • The asynchronous reset (R) input should be tied to VCC through a resistor (e.g., 1kΩ) and a capacitor (e.g., 0.01uF) to ensure proper reset functionality.
  • The enable (E) input is used to enable or disable the counter. When E is high, the counter is enabled, and when E is low, the counter is disabled and the outputs are in a high-impedance state.
