Product Description

The MC74ACT257DR2 is a versatile device that can be used in a wide variety of digital applications. It features a common select input (S) and four individual enable inputs (1G, 2G, 3G, 4G). When the enable input is high, the associated 3-state output (Y) is active and reflects the data present at the selected input (A or B). When the enable input is low, the output is in a high-impedance state, effectively isolating it from the circuit.

This multiplexer is fabricated with silicon gate CMOS technology, which ensures reduced power consumption while maintaining high speed. The MC74ACT257DR2 operates efficiently within the industrial temperature range and is characterized for operation from -55°C to 125°C.

With its compact SOIC-16 package, the MC74ACT257DR2 is designed for surface-mount technology, making it ideal for use in space-constrained applications. It is also lead-free and meets RoHS compliance, ensuring environmental friendliness and suitability for use in a wide range of commercial and industrial products.

Whether you're designing complex data routing systems, communication devices, or need a reliable multiplexer for your digital logic applications, the ON Semiconductor MC74ACT257DR2 offers a combination of performance, versatility, and reliability that can meet your needs.
