Description
5 x SN74HC139 Dual 2-Line to 4-Line Decoder/Demultiplexer IC in DIP-16 package, designed for digital logic, address decoding, and general-purpose electronics projects.
The SN74HC139 contains two independent 2-to-4 decoders, each with an active LOW enable (strobe) input. When the strobe input disables a channel, all outputs are forced HIGH. When enabled, only the selected output goes LOW while the remaining outputs stay HIGH.
Ideal for logic expansion, memory addressing, and DIY electronics builds.
