SN74HC139D Description

Short technical summary and product information.

The SN74HC139D from Texas Instruments is a dual 2-line to 4-line decoder/demultiplexer designed for high-speed memory decoders and data-transmission systems. It features a wide operating voltage range from 2V to 6V, making it versatile for various applications.

 

This device contains two independent 2-to-4 decoders, each with an active-low output strobe. When the strobe is inactive, only the selected output is low while others remain high. This functionality simplifies cascading and data reception.

 

The SN74HC139D is available in a 16-SOIC package, designed for surface mounting. It operates within a temperature range of -40°C to 85°C, ensuring reliable performance in demanding environments. Its outputs can drive up to 10 LSTTL loads, and it offers a typical propagation delay of 10 ns.

 

Key electrical characteristics include a low power consumption of 80 μA maximum ICC, ±4 mA output drive at 5V, and a low input current of 1 μA maximum. These features make the SN74HC139D an efficient choice for digital logic designs.
