Description:
The SN74HC139N is a high-speed CMOS dual 2-to-4 line decoder/demultiplexer IC featuring two independent decoding sections. Each decoder accepts two binary address inputs and provides four mutually exclusive active-low outputs, making it ideal for memory address decoding, signal routing, or demultiplexing in digital logic circuits.
Encapsulated in a standard DIP14 package, the SN74HC139N is designed for through-hole mounting and is fully compatible with breadboards and prototyping boards. With fast switching performance, TTL-level compatibility, and low power consumption, this IC is well-suited for embedded systems, control panels, and learning environments. Supplied in a pack of 5, it offers great value for logic development or circuit repairs.
