Specifications

The CD4020BE is a 14-stage ripple-carry binary counter/divider and oscillator. It is designed using CMOS technology, which provides low power consumption and high noise immunity. The IC comes in a DIP package and is available in tube packaging with 25 pieces per tube.

Detailed Pin Configuration

The CD4020BE has a total of 16 pins, each serving a specific function. The pin configuration is as follows:

1. Q5
2. Q4
3. Q3
4. Q2
5. Q1
6. Q0
7. MR (Master Reset)
8. CP (Clock Pulse)
9. Q6
10. Q7
11. Q8
12. Q9
13. Q10
14. Q11
15. VDD (Positive Power Supply)
16. VSS (Ground)

Functional Features

The CD4020BE functions as a binary counter and divider. It can count up to 2^14 (16,384) states and divide an input frequency by powers of 2. The IC also includes an oscillator feature, allowing it to generate clock pulses internally.

Advantages and Disadvantages

Advantages: - Low power consumption due to CMOS technology - High noise immunity - Versatile functionality as a counter, divider, and oscillator - Compact DIP package for easy integration

Disadvantages: - Limited maximum count of 16,384 states - Requires an external clock pulse for operation

Working Principles

The CD4020BE operates by counting the number of clock pulses received at the CP pin. Each clock pulse increments the counter by one. The output pins (Q0-Q11) represent the binary value of the current count. When the maximum count is reached, the counter resets to zero if a master reset signal (MR) is applied.

Detailed Application Field Plans

The CD4020BE finds applications in various fields where binary counting, dividing, and oscillation are required. Some specific application areas include:

1. Digital frequency division circuits
2. Time delay generation circuits
3. Frequency synthesizers
4. Event sequencing systems
5. Pulse generation circuits
