What are the key features of SN7425NG4?

  • Dual independent 4-input NOR gate channels for versatile combinational logic implementation in a single package
  • Classic TTL 7400 series compatibility ensures broad design reuse and interoperability with legacy and modern systems
  • 14-pin DIP package provides easy prototyping and through-hole assembly for industrial and educational applications

What is SN7425NG4 used for?

The SN7425NG4 is used in digital logic systems requiring NOR-based combinational logic, including decoders, multiplexers, and control circuits in computing and industrial automation. Its dual 4-input NOR gates are well-suited for implementing sum-of-products logic functions and bus control circuitry. The through-hole DIP package makes it ideal for prototyping, repair work, and educational applications where breadboard access is needed.

Frequently Asked Questions

How many NOR functions are available inside SN7425NG4?

SN7425NG4 contains 2 independent NOR gate channels, and each channel accepts 4 inputs for implementing TTL logic combining and decode functions.

Which supply and package constraints matter for a legacy TTL board?

The part is described for a standard 5V supply and a 14-pin DIP package, so it fits through-hole 7400-series TTL replacement or maintenance designs.

When is SN7425NG4 a suitable procurement choice instead of redesigning the logic?

It is useful when an existing board already depends on 4-input NOR behavior, 5V TTL levels, and the same 14-pin DIP mechanical footprint.
