The CD74ACT139E is a high-performance, CMOS dual 2-line to 4-line decoder/demultiplexer designed and manufactured by Texas Instruments. This integrated circuit is engineered to provide efficient solutions for a wide range of digital applications, particularly where high-speed, low-power consumption, and reduced noise are essential.

Key Features

• Logic Type: Decoder/Demultiplexer
• Logic Family: ACT
• Operating Voltage: 4.5V to 5.5V
• High-Speed: t_PD = 9ns (typ) at V_CC = 5V
• I_CC Reduced by 50%: The device is optimized to consume half the I_CC of the standard AC/ACT family devices, making it ideal for battery-powered and power-sensitive applications.

Product Description

The CD74ACT139E is designed to be used in high-performance memory-decoding or data-routing applications requiring very short propagation delay times. Its dual 2-line to 4-line configuration allows for efficient utilization in systems that require lower power consumption and high-speed operation.

In its typical application, the device takes two binary input signals and decodes them to select one of four output lines, making it an essential component for managing data flow in complex digital systems. The device features two independent decoders, each accepting two binary weighted inputs (A0, A1) and providing four mutually exclusive active LOW outputs (O0 to O3).

The CD74ACT139E is characterized for operation from -55°C to 125°C, ensuring reliability across a wide range of environmental conditions. Its standard 16-pin DIP (Dual In-line Package) makes it compatible with a variety of socket and board configurations, allowing for flexible integration into existing and new designs.

Applications

Thanks to its versatility and performance characteristics, the CD74ACT139E is suitable for a broad array of applications, including:

• Memory decoding
• Data routing
• Control systems
• Computer systems
• Instrumentation
• Telecommunications
