CD4518BEG4

The CD4518BEG4 is a dual 4-bit binary full adder integrated circuit (IC) manufactured by Texas Instruments. This device is part of the CD4000 series of CMOS logic ICs, which are known for their low power consumption and high noise immunity.

Key Features:

• Dual 4-Bit Configuration: The CD4518 contains two independent 4-bit binary full adders, allowing it to perform addition on two 4-bit binary numbers simultaneously.
• Wide Supply Voltage Range: It operates over a supply voltage range of 3V to 15V, making it versatile for various applications.
• Low Power Consumption: The CMOS technology used in this IC ensures low static and dynamic power consumption, which is beneficial for battery-operated devices.
• High Noise Immunity: The design provides good noise margins, making it reliable in noisy environments.
• Propagation Delay: The typical propagation delay is around 50 ns at 5V, which is suitable for many digital applications.
• Pin Configuration: The IC typically comes in a 16-pin dual in-line package (DIP), with pins designated for inputs, outputs, and power supply connections.

Functional Description:

The CD4518BEG4 can take two 4-bit binary numbers as inputs and produce a 4-bit sum output along with a carry output. Each adder has two sets of inputs (A and B) and a carry input (C_in), allowing for cascading multiple adders for larger binary numbers. The outputs are represented in binary form, and the carry output can be used to indicate an overflow condition when the sum exceeds the maximum value representable by 4 bits.

Applications:

This IC is commonly used in digital circuits for arithmetic operations, such as in calculators, digital signal processors, and various computing applications. It can also be utilized in educational settings for teaching digital logic design and binary arithmetic.

Package Information:

The CD4518BEG4 is available in various package types, with the "BEG4" suffix indicating a specific package style and lead finish. It is typically RoHS-compliant, ensuring it meets environmental standards for hazardous substances.

Conclusion:

The CD4518BEG4 from Texas Instruments is a robust and efficient dual 4-bit binary full adder that is suitable for a wide range of digital applications. Its combination of low power consumption, high noise immunity, and flexible operating voltage makes it a popular choice among engineers and hobbyists alike.
