SN74HC139DR Description

Short technical summary and product information.

The SN74HC139DR from Texas Instruments is a dual 2-line to 4-line decoder/demultiplexer integrated circuit. This device is designed for high-speed memory decoders and data-transmission systems, offering a wide operating voltage range from 2V to 6V. Each decoder within the SNx4HC139 contains two independent 2-to-4 decoders, each with an active-low output strobe. When the strobe input is active, all outputs are forced high; otherwise, only the selected output is low while others remain high.

 

Key electrical characteristics include a low typical propagation delay of 10 ns, a low input current of 1 μA maximum, and low power consumption with a maximum ICC of 80 μA. The outputs can drive up to 10 LSTTL loads and provide ±4 mA output drive at 5V. The device is available in a 16-SOIC package and is designed for surface mounting.

 

This decoder/demultiplexer is targeted for applications requiring efficient data selection and decoding. Its dual enable inputs simplify cascading and data reception, making it a versatile component for digital logic designs. The operating temperature range is -40°C to 85°C, ensuring reliable performance in various environmental conditions.
