Key Features
- Quad 2-to-1 multiplexer selects among two 4-bit data buses with a single common select signal for compact data routing
- Inverted (complementary) outputs provide direct active-low logic integration without additional inverters
- HC CMOS logic family supports 2 V to 6 V operation with high noise immunity for robust digital switching
- 16-pin DIP through-hole package simplifies prototyping, breadboarding, and legacy board repair
Applications
The SN74HC158NG4 is used in digital systems for data routing, bus switching, and signal multiplexing where one of two input sources must be selected and presented at the output. Typical applications include address multiplexing in memory systems, data selector logic in PLDs and FPGAs, and general-purpose mux functions in educational and prototyping projects.

Frequently Asked Questions
What does the SN74HC158NG4 do?
The SN74HC158NG4 is a quad 2-to-1 data selector/multiplexer. It routes one of two 4-bit input data buses to the outputs based on the state of a common select pin. The outputs are inverted, meaning the selected input data appears complemented at the output.
What logic family does the SN74HC158NG4 belong to?
The SN74HC158NG4 belongs to the HC (High-Speed CMOS) logic family. HC devices operate from 2 V to 6 V, offering low power consumption, high noise immunity, and fast switching speeds. They are compatible with both CMOS and TTL input levels when operated at 5 V.
What package does the SN74HC158NG4 use?
The SN74HC158NG4 is available in a 16-pin DIP (Dual In-Line Package) through-hole package. This package is widely used in prototyping and through-hole PCB assembly, and is compatible with standard breadboards and IC sockets.
How is the SN74HC158NG4 controlled?
The SN74HC158NG4 uses a single common SELECT input to choose between the two sets of inputs (I0 and I1) for all four channels simultaneously. It also has an active-low STROBE (enable) input; when STROBE is high, all outputs are forced to the high logic state regardless of the select or data inputs.
