How to Use 4060: Examples, Pinouts, and Specs

The CD4060BE is an integrated circuit (IC) that features a 14-stage binary ripple counter along with an on-chip oscillator that can be used to produce time delays or as a frequency divider in various timing applications. This versatile component is commonly used in timer circuits, frequency counters, time-delay applications, and as an oscillator in microprocessor systems.

• Supply Voltage (Vdd): 3V to 18V
• Input Voltage (Vin): -0.5V to Vdd + 0.5V
• Operating Temperature: -55°C to +125°C
• Frequency Range: Typically up to 10MHz (varies with Vdd)
• Counter Stages: 14
• Package: Available in various packages, including DIP and SOIC

1. Power Supply: Connect pin 16 (Vdd) to a positive supply voltage within the range of 3V to 18V. Connect pin 8 (GND) to the ground of your circuit.

2. Oscillator Configuration: To use the internal oscillator, connect a resistor between pin 16 (Vdd) and pin 10 (Rext/CLKIN) and a capacitor from pin 9 (Cext) to ground. The frequency of the oscillator can be calculated using the formula provided in the datasheet.

3. Counter Outputs: The Q outputs (Q0 to Q14) provide the binary count as the counter progresses. These can be used to derive timing intervals or as frequency dividers.

4. Resetting the Counter: To reset the counter, a low level (0V) must be applied to the reset pin (MR). This will set all Q outputs to low.

• Ensure that the power supply voltage does not exceed the maximum rating of 18V.
• Decouple the power supply with a 0.1µF capacitor close to the IC to filter out noise.
• Avoid applying signals to the input pins that exceed the supply voltage or go below ground level.

• Counter Not Advancing: Ensure that the oscillator is correctly configured and that the power supply is within the specified range.
• Unexpected Reset: Noise on the MR (Master Reset) pin can cause the counter to reset unexpectedly. Use a pull-up resistor and proper decoupling to mitigate this.

Q: Can the 4060 IC be used with an Arduino? A: Yes, the 4060 can be interfaced with an Arduino. The Q outputs can be connected to the digital input pins of the Arduino to read the counter state.

Q: What is the maximum frequency the 4060 can handle? A: The maximum frequency typically goes up to 10MHz, but it varies with the supply voltage and temperature.

Q: How can I calculate the output frequency? A: The output frequency is determined by the values of the external resistor and capacitor connected to the oscillator pins. Refer to the datasheet for the formula and example calculations.

// Example code to read the state of the Q outputs from a CD4060BE IC

const int outputPins[] = {2, 3, 4, 5, 6, 7, 8, 9}; // Connect these to Q0-Q7 respectively

void setup() {
  Serial.begin(9600);
  for (int i = 0; i < 8; i++) {
    pinMode(outputPins[i], INPUT);
  }
}

void loop() {
  unsigned long counterValue = 0;
  for (int i = 0; i < 8; i++) {
    counterValue |= digitalRead(outputPins[i]) << i;
  }
  Serial.println(counterValue);
  delay(1000); // Read the counter value every second
}

This code snippet demonstrates how to read the first 8 stages of the counter outputs from the CD4060BE using an Arduino. The outputs Q0 to Q7 are connected to digital input pins 2 to 9 on the Arduino. The counter value is read every second and printed to the Serial Monitor.
