SN74AHC139N Description

Short technical summary and product information.

The SN74AHC139N is a dual 2-line to 4-line decoder/demultiplexer IC manufactured by Texas Instruments. Designed for high-speed memory decoding and data-transmission systems, it operates efficiently within a voltage range of 2V to 5.5V.

 

This component features two independent 2-to-4 line decoders, each with two enable inputs that facilitate cascading or data reception. The device is suitable for applications requiring very short propagation delay times, minimizing system decoding effects in high-performance memory systems.

 

The SN74AHC139N is available in a 16-PDIP through-hole package, making it suitable for standard PCB mounting. Its operating temperature range is from -40°C to 125°C, ensuring reliable performance in various environmental conditions.

 

Key electrical characteristics include a maximum supply current of 40µA and latch-up performance exceeding 250mA. ESD protection is robust, with 2000V for the human-body model and 1000V for the charged-device model.
