ON Semiconductor MC74ACT240N Octal Buffer/Line Driver

The MC74ACT240N is a high-performance, octal buffer/line driver designed by ON Semiconductor to provide efficient solutions for a variety of digital systems. This integrated circuit is part of the ACT (Advanced CMOS Technology) family, which delivers the speed of bipolar FET devices while maintaining the low power consumption of CMOS technology.

Featuring eight non-inverting buffers with 3-state outputs, the MC74ACT240N is capable of driving bus lines or buffer memory address registers with exceptional proficiency. Each buffer has a separate output-enable (OE) input, which controls whether the buffer is active and driving the output or disabled to allow the output to enter a high-impedance state. This high-impedance state is crucial for shared bus applications, where multiple devices may need to connect to the bus without interference.

The device is designed to be used with 5V power supplies and can operate within a voltage range of 4.5V to 5.5V. It features a typical t_pd (propagation delay time) of 8ns, which ensures rapid signal processing, making it suitable for high-speed data transfer applications. The MC74ACT240N is also characterized for operation from -40°C to 85°C, providing reliable performance across a wide range of environmental conditions.

Encased in a 20-pin DIP (Dual In-line Package), the MC74ACT240N offers a robust and practical design for through-hole mounting, which is ideal for prototyping and educational use, as well as for commercial production. This package is well-suited for breadboards and standard PCBs, allowing for easy integration into a variety of electronic projects and products.

ON Semiconductor's commitment to quality ensures that the MC74ACT240N meets stringent standards, providing designers with a dependable and efficient solution for their digital interfacing needs. Whether it's for bus driving, memory addressing, or other digital functions, the MC74ACT240N stands as a versatile and reliable component in the electronics industry.
