Features
1. Dual Counters: It contains two separate 4-bit counters, which can be configured independently.
2. Binary Counting: Each counter can count from 0 to 15 (4-bit binary count).
3. Synchronous Operation: Both counters operate synchronously with their respective clock inputs, ensuring precise timing.
4. Master Reset: Each counter has its own reset pin, allowing the count to be reset to zero asynchronously.
5. Wide Operating Voltage: It operates over a wide voltage range, typically from 3V to 15V, making it versatile for various applications.
6. Low Power Consumption: Designed for low power consumption, it is suitable for battery-operated devices.
7. High Noise Immunity: The device features high noise immunity, making it reliable in various environments.
8. TTL Compatibility: It is compatible with TTL logic levels, ensuring easy integration with other components.
9. Compact Package: Available in a 16-pin DIP package, it is easy to use in both breadboard and PCB applications.
These features make the CD4520BE a widely used component in counters, timers, and frequency dividers.
Pinout
1. Pins 1-3, 9-11: Counter A input and output pins.
2. Pins 4, 12: Clock inputs for counters A and B, respectively.
3. Pins 5, 13: Reset inputs for counters A and B, respectively.
4. Pins 6-8, 14-16: Counter B input and output pins.
5. Pin 7: Ground (GND) connection.
6. Pin 14: Power supply (VDD) connection.
Each counter has a clock input, a reset input, and four output lines representing the 4-bit count. By using the clock and reset pins, users can control the counting operation, making the CD4520BE suitable for various digital applications requiring binary counting.
