SN74159N TI TTL 4-to-16 Line Decoder IC

The SN74159N is a classic 4-to-16 line decoder/demultiplexer IC manufactured by Texas Instruments, designed for digital logic applications requiring precise signal routing and line decoding. Built on trusted TTL technology, this DIP-24 packaged IC accepts a 4-bit binary input and activates one of 16 output lines, making it an essential component for address decoding, memory selection, and data routing in digital systems.

Ideal for electronics engineers, students, and hobbyists working on retro computing projects, logic circuit design, or embedded system development, the SN74159N offers open-collector outputs that allow flexible wiring configurations and easy interfacing with a wide range of TTL and CMOS logic families.

Its robust design, wide availability, and well-documented behaviour make it a reliable choice for both prototyping on breadboards and permanent PCB installations. A staple component in any well-stocked electronics lab or hobbyist parts collection.
