DM74S258N

Overview

The DM74S258N is a dual four-input multiplexer manufactured by onsemi, belonging to the 74S Schottky TTL logic family. It features two independent multiplexers, each capable of selecting one of four input signals based on select lines. The device operates within a supply voltage range of 4.75V to 5.25V and supports through-hole mounting in a 16-DIP package. It functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Dual independent four-to-one data selection capability
• Schottky TTL technology for high-speed switching performance
• Standard 16-pin DIP packaging for through-hole integration

Applications

• Digital signal routing in logic circuits
• Data selection systems requiring multiple input channels
• Multiplexing applications in industrial control equipment

Procurement Notes
