HEF4528BT,653

The HEF4528BT,653 is a dual 4-input NAND gate integrated circuit (IC) manufactured by Nexperia, a well-known semiconductor company. This device is part of the 4000 series of CMOS logic ICs, which are characterized by their low power consumption and high noise immunity.

Key Features:

1. Functionality: The HEF4528BT contains two independent 4-input NAND gates. Each gate can take four input signals and produce a single output signal that is the logical NAND of the inputs. This means that the output is low (0) only when all four inputs are high (1).

2. Pin Configuration: The IC typically comes in a 14-pin Dual In-line Package (DIP) format, which allows for easy integration into various electronic circuits. The pins are arranged in two rows, with each pin serving a specific function, including power supply, ground, inputs, and outputs.

3. Supply Voltage: The HEF4528BT operates over a wide supply voltage range, typically from 3V to 15V, making it versatile for different applications. This flexibility allows it to be used in both battery-powered devices and standard power supply circuits.

4. Logic Levels: The IC is designed to work with standard CMOS logic levels, ensuring compatibility with other CMOS devices. It features a high input impedance, which minimizes the load on preceding stages in a circuit.

5. Propagation Delay: The propagation delay of the HEF4528BT is relatively low, allowing for fast switching times. This makes it suitable for high-speed applications where quick response times are critical.

6. Temperature Range: The device is rated for operation over a standard temperature range, typically from -40°C to +125°C, making it suitable for a variety of environments, including industrial applications.

7. Applications: The HEF4528BT is commonly used in digital logic circuits, including combinational logic, data processing, and control systems. It can be found in applications such as signal processing, data routing, and various consumer electronics.

8. Package Type: The "BT" in the part number indicates the package type, which is a plastic DIP. This package is favored for prototyping and through-hole applications due to its ease of handling and soldering.

Summary:

The HEF4528BT,653 from Nexperia is a reliable and efficient dual 4-input NAND gate IC that offers versatility in design and application. Its low power consumption, wide supply voltage range, and compatibility with standard CMOS logic levels make it an excellent choice for a variety of electronic projects and products. Whether used in simple logic circuits or more complex digital systems, the HEF4528BT provides a robust solution for engineers and designers.
