SN74HC139N Description

Short technical summary and product information.

The SN74HC139N from Texas Instruments is a high-speed dual 2-line to 4-line decoder/demultiplexer. It is specifically targeted for applications such as memory decoders and data-transmission systems. This device features a wide operating voltage range from 2 V to 6 V, making it versatile for various designs.

 

The SN74HC139N contains two independent 2-to-4 decoders, each with an active low output strobe. When the strobe input is not disabled, only the selected output is low while all others remain high. This functionality simplifies cascading and data reception.

 

With a typical propagation delay of 10 ns and an output drive capability of ±4 mA at 5 V, the SN74HC139N is suitable for performance-critical applications. It also boasts low power consumption, with a maximum ICC of 80 μA and a low input current of 1 μA max.

 

The component is available in a 16-PDIP package and is designed for Through Hole mounting. It operates within an ambient temperature range of -40°C to 85°C.
