MC74LCX139D Description

Short technical summary and product information.

The MC74LCX139D from ON Semiconductor is a high-performance, dual 2-to-4 decoder/demultiplexer. It operates within a voltage range of 2.3V to 3.6V, making it suitable for low-voltage systems. The device features 5V tolerant inputs, allowing for interface capability with 5V TTL logic.

 

Each of the two independent 2-to-4 decoders accepts two binary weighted inputs and provides four mutually exclusive active-low outputs. The device includes an active-low enable input. All outputs will be HIGH unless the enable is LOW. The MC74LCX139D is designed for applications such as memory address decoding and other TTL level bus-oriented tasks.

 

This decoder/demultiplexer comes in a 16-SOIC surface mount package with a standard operating temperature range of -40°C to 85°C. It offers a current drive capability of 24mA for both sink and source operations. The high-impedance TTL-compatible inputs minimize current loading on input drivers, while TTL-compatible outputs enhance switching noise performance.
