ON Semiconductor MC74HC257FR2 Multiplexer

The MC74HC257FR2 is a high-performance, quad 2-input multiplexer integrated circuit from ON Semiconductor. This versatile component is designed to function in a wide range of digital applications, offering exceptional signal multiplexing capabilities. It is part of the HC family of logic devices, known for their high-speed and low power consumption, making it an ideal choice for power-sensitive designs.

Featuring four multiplexers with common select and enable inputs, the MC74HC257FR2 allows for precise control of multiple data lines with minimal external circuitry. Each multiplexer has two input lines (A and B) and one output line (Y). The select input (S) determines which of the input lines A or B is connected to the output Y, while the enable input (E) is used to control the output state—either active or high impedance.

The device operates over a broad voltage range, from 2V to 6V, catering to a variety of logic level requirements, which is especially useful in interfacing with both TTL and CMOS technologies. This flexibility ensures that the MC74HC257FR2 can be integrated into a wide array of digital systems without compatibility concerns.

Packaged in a compact, surface-mount SOIC-16 package, the MC74HC257FR2 is designed for optimal space-saving on printed circuit boards. It is also characterized for operation from -55°C to 125°C, making it reliable in extreme environmental conditions and suitable for industrial-grade applications.

ON Semiconductor's commitment to quality is evident in the MC74HC257FR2, as it meets stringent standards for performance and durability. The device is also supported by comprehensive technical documentation, including datasheets and application notes, to facilitate easy integration into your designs.

In summary, the MC74HC257FR2 from ON Semiconductor is a robust, high-speed multiplexer that offers design flexibility, operational efficiency, and reliability—making it an excellent choice for designers looking to optimize their digital systems.
