SN74AS158N

Overview

The SN74AS158N is a quad 1-of-2 data selector/multiplexer manufactured by Texas Instruments. It features four independent multiplexers, each capable of selecting one of two data inputs based on a common select line. The device operates within a supply voltage range of 4.5 V to 5.5 V and exhibits a propagation delay time of 15 ns. It is housed in a 16-pin PDIP package and is designed for high-speed silicon-gate CMOS applications requiring efficient data routing.

Feature Summary

• Provides four independent 2-to-1 data selection channels
• Utilizes common select lines for synchronized channel switching
• Designed for high-speed data routing applications

Applications

• Data routing in digital systems
• Multiplexing signals for processing
• Address decoding circuits

Procurement Notes

Verify the specific manufacturer source and authenticity when sourcing this component. Confirm that the part number matches the exact SN74AS158N designation to ensure compatibility with existing circuit designs. Check for any available datasheets from authorized distributors to validate technical specifications against your system requirements before finalizing procurement decisions.

Selection Notes

Select this component when a quad multiplexer with moderate speed requirements is needed. The 15 ns propagation delay suits general-purpose logic applications. Ensure the power supply remains within the 4.5 V to 5.5 V range for proper operation. Consider the PDIP package size if through-hole mounting is required for the design.

Part Context

This part belongs to the SN74AS series of logic devices, known for advanced Schottky technology. It serves as a standard solution for multi-channel data selection tasks in digital electronics. The device integrates multiple multiplexers into a single package to reduce board space and simplify wiring compared to discrete solutions.

Replacement Considerations

Check for SN74AS158N-J as a potential variant. Verify pinout and electrical characteristics match exactly before substitution. No other direct substitutes are confirmed in public documentation.
