ON Semiconductor MC74ACT139N Dual 1-of-4 Decoder/Demultiplexer Product Overview

The ON Semiconductor MC74ACT139N is a high-performance, dual 1-of-4 decoder/demultiplexer integrated circuit that is designed to address the needs of complex digital systems. This versatile component is fabricated with advanced CMOS technology to achieve high-speed operation while maintaining CMOS low power dissipation.

This integrated circuit is organized as two individual 1-of-4 decoders, each with its own address inputs and an enable input. The enable input can be used as a data input for demultiplexing applications. Each decoder has four mutually exclusive outputs, which are active low. This means that when the enable input is high, all outputs of the decoder are high as well. When the enable input is low, one of the four outputs will go low, as determined by the combination of the address inputs.

With a wide operating voltage range of 4.5V to 5.5V, the MC74ACT139N is compatible with most 5V systems. The device can also interface with TTL levels, making it suitable for use in mixed 5V and 3.3V environments. The MC74ACT139N has a typical propagation delay time of 8ns, allowing for fast response times in critical applications. Additionally, the device is characterized for operation from -55°C to 125°C, ensuring reliable performance across a broad range of environmental conditions.

The MC74ACT139N comes in a standard 16-pin DIP (Dual In-line Package), which is easy to handle and compatible with conventional through-hole PCB assembly processes. This makes the device a good choice for prototyping as well as mass production.

Applications of the MC74ACT139N are diverse and include memory chip select decoding, data routing, control logic, and many other digital systems where high-speed, low-power decoding/demultiplexing is required. The reliability and performance of ON Semiconductor's components make the MC74ACT139N a dependable choice for designers and engineers looking to enhance their digital systems.
