Description

The CD4518BE is a dual 4-bit binary full adder IC (Integrated Circuit) from the CD4000 series of CMOS (Complementary Metal-Oxide-Semiconductor) logic devices. It is designed to perform binary addition on two 4-bit numbers and provides carry output for cascading with other adders, facilitating the addition of larger binary numbers.
Key features include low power consumption, wide supply voltage range (typically 3V to 15V), and high noise immunity. The device incorporates two independent full adder circuits, allowing simultaneous addition of two 4-bit binary inputs. Each adder has inputs for the two binary numbers and a carry input, and provides a 4-bit sum output along with a carry output.
The CD4518BE is commonly used in digital circuits, arithmetic logic units (ALUs), and other applications requiring binary arithmetic. Its compatibility with other CD4000 series devices allows for easy integration into larger digital systems.

Features

The CD4518BE is a dual 4-bit binary counter in a 16-pin Dual In-line Package (DIP). Key features include:
1. Dual Functionality: It functions as two independent 4-bit binary counters, allowing for flexible counting applications.
2. Wide Voltage Range: Operates over a supply voltage range of 3V to 15V, suitable for various electronic projects.
3. Asynchronous Reset: Offers an asynchronous reset feature to clear the counter at any time.
4. Clock Input: Counts on the rising edge of the clock signal, providing precise timing control.
5. Synchronous Enable: Features synchronous enable inputs, allowing for coordinated counting operations.
6. Output States: Provides binary output states (Q0-Q3) for display or further processing.
7. Low Power Consumption: Designed for low power usage, making it ideal for battery-operated devices.
8. Temperature Range: Operates effectively across a temperature range of -55°C to +125°C.
The CD4518BE is widely used in digital circuits for counting applications, frequency division, and timer functions.

Package

The CD4518BE is typically packaged in a dual in-line package (DIP) format, specifically a 16-pin DIP. It may also be available in surface mount packages like the SOIC or TSSOP, depending on the manufacturer.

Pinout

The CD4518BE is a dual 4-bit binary counter with a total of 16 pins. Its pin configuration is as follows:
1. Pin 1 (A1): Input for the first bit of counting.
2. Pin 2 (A0): Input for the second bit of counting.
3. Pin 3 (B1): Input for the third bit of counting.
4. Pin 4 (B0): Input for the fourth bit of counting.
5. Pin 5 (C1): Carry output.
6. Pin 6 (C0): Carry input.
7. Pin 7 (VSS): Ground.
8. Pin 8 (VDD): Power supply (typically +3V to +15V).
9. Pin 9 (Q3): Output for the third bit.
10. Pin 10 (Q2): Output for the second bit.
11. Pin 11 (Q1): Output for the first bit.
12. Pin 12 (Q0): Output for the fourth bit.
13. Pin 13 (RESET): Reset input (active low).
14. Pin 14 (ENABLE): Enable counting (active high).
15. Pin 15 (LOAD): Load input for preset functions (active low).
16. Pin 16 (NC): No connection.
The CD4518BE functions primarily as a counter, capable of counting in binary and providing outputs for each bit.
