Description

The CD4520BE is a dual 4-bit binary ripple counter and frequency divider integrated circuit (IC) designed for various digital applications. It is part of the CD4000 series, known for its CMOS technology that ensures low power consumption and high noise immunity. The CD4520BE features two independent 4-bit counters, which can be configured to count up or down, providing flexibility for different counting applications.
Each counter is equipped with a clock input, asynchronous reset, and carry-out features, allowing them to be cascaded for extended counting capabilities. The IC operates over a wide supply voltage range (3V to 15V), making it suitable for battery-powered devices as well as standard power supply applications.
Common uses include frequency division, event counting in digital circuits, and timer applications. The CD4520BE's versatility in handling binary counting tasks makes it a valuable component in embedded systems and electronic projects.

Features

The CD4520BE is a dual 4-input NAND gate integrated circuit. Key features include:
1. Dual Functionality: Contains two independent 4-input NAND gates.
2. Wide Operating Voltage: Functions typically within a voltage range of 3V to 15V.
3. High Noise Immunity: Designed for improved noise margins, making it suitable for various applications.
4. Low Power Consumption: Consumes low static and dynamic power, ideal for battery-operated devices.
5. TTL Compatible: Compatible with Transistor-Transistor Logic (TTL), allowing easy integration into existing circuits.
6. Temperature Range: Operates efficiently over a wide temperature range, typically from -55°C to +125°C.
7. Pin Configuration: Standard 14-pin Dual-Inline Package (DIP) facilitates easy mounting and prototyping.
8. Propagation Delay: Fast switching times, enhancing performance in high-speed applications.
This makes the CD4520BE suitable for various digital applications, including logic circuits, signal processing, and control systems.

Package

The CD4520BE is typically available in a dual in-line package (DIP) format, specifically the 16-pin DIP. It may also be found in surface mount options like the SOIC or TSSOP, depending on the manufacturer.

Pinout

The CD4520BE is a dual 4-bit binary ripple counter IC. It contains two counters, each with a pin count of 16. The key pin functions are as follows:
1. Power Supply Pins:
- VDD (Pin 14): Positive supply voltage.
- VSS (Pin 7): Ground reference.
2. Counter Inputs and Outputs:
- A, B, C, D (Pins 1-4 for Counter 1, Pins 10-13 for Counter 2): Data input for the counter.
- Q0, Q1, Q2, Q3 (Pins 5-8 for Counter 1, Pins 15-16 for Counter 2): 4-bit output for each counter.
3. Control Pins:
- RESET (Pins 9 and 12): Asynchronous reset for both counters.
- CLOCK (Pins 4 and 13): Clock input for counting operation.
4. Carry Output:
- CARRY (Pin 11): Carry output for cascading multiple counters.
These functions allow the CD4520BE to be used effectively in various digital counting applications.
