Description and Introduction

Quad 2-line to 1-line selector/multiplexer, non-inverting 3-State The **N74F257AD** is a high-performance quad 2-input multiplexer with 3-state outputs, designed for use in a variety of digital logic applications. This integrated circuit (IC) belongs to the **74F series**, known for its fast switching speeds and robust performance in demanding environments.  

Featuring four independent multiplexers in a single package, the N74F257AD allows data selection from two sources per channel, controlled by a common select input. The 3-state outputs enable efficient bus-oriented systems by permitting multiple devices to share a common data line without interference.  

Key characteristics include **low power consumption**, **high noise immunity**, and **compatibility with TTL logic levels**, making it suitable for interfacing with a wide range of digital systems. With propagation delays typically under 10 nanoseconds, the IC is ideal for high-speed data routing in microprocessors, memory systems, and communication interfaces.  

Housed in a **16-pin SOIC (Small Outline Integrated Circuit) package**, the N74F257AD offers a compact footprint for space-constrained designs while maintaining reliable operation across industrial temperature ranges. Its versatility and performance make it a valuable component in digital circuit design, particularly where efficient data handling and signal routing are critical.  

Engineers and designers often choose this IC for its balance of speed, power efficiency, and functional integration.

Application Scenarios & Design Considerations

Quad 2-line to 1-line selector/multiplexer, non-inverting 3-State

Alternative Part Number

  • SN74F257AD --: Same 74F257 quad 2-to-1 multiplexer function in SOIC package, direct pin-compatible replacement from a major logic vendor.
  • MC74F257AD --: Equivalent 74F257 multiplexer with identical logic function and SOIC pinout, widely available second source.
  • 74F257AD --: NXP (formerly Philips) 74F257 in SOIC package, same function and pinout, suitable as a drop-in substitute.
