The CD74ACT257M is a high-performance CMOS Quad 2-Input Multiplexer with 3-state outputs from Texas Instruments. This device is designed to deliver the functionality of two input lines to a single common output line for each of the four multiplexers. It is a versatile component commonly used in data routing, signal gating, and information processing applications.

Constructed with the advanced silicon-gate CMOS technology, the CD74ACT257M offers a robust feature set including:

• High Speed: With a typical t_pd of 8.5ns at 5V, it provides swift multiplexing capabilities.
• Low Power Consumption: Its I_CC is low, even at high speeds, making it suitable for battery-powered and energy-efficient designs.
• Wide Operating Voltage Range: It can function over a broad voltage range from 4.5V to 5.5V, providing versatility in different circuit environments.
• 3-State Outputs: The outputs can be placed in a high impedance state, allowing for use in bus-oriented systems.
• Input Hysteresis: It features built-in hysteresis to combat noise, ensuring stable output states.

The CD74ACT257M is provided in a 16-pin SOIC package, which is suitable for a wide range of applications, including industrial, commercial, and telecommunications systems. Its pin configuration is designed for easy PCB layout and space-saving, which is critical for compact and complex electronic assemblies.

As with many Texas Instruments components, the CD74ACT257M is characterized for operation from -40°C to 85°C, ensuring reliability across extreme temperature ranges. This makes it an excellent choice for demanding environments where temperature fluctuations are a concern.

Whether you are designing a multiplexing system for data selection, signal gating, or require a reliable component for your digital circuitry, the CD74ACT257M from Texas Instruments is a high-quality choice that combines performance with durability.
