Product Overview

National Semiconductor DM74ALS32N - quad 2-input OR gate in a 14-pin plastic DIP package. ALS (Advanced Low-Power Schottky) TTL technology. Four independent gates on one chip. Each gate drives its output high when either or both inputs are high. Standard 5V logic, through-hole mounting.

Key Features

• Logic function: Quad 2-input OR gate - four independent gates per package
• Technology: ALS TTL (Advanced Low-Power Schottky) - faster than LS, lower power than S
• Package: 14-pin PDIP, through-hole - breadboard and socket compatible
• Operating voltage: 5V (4.5V to 5.5V)
• Propagation delay: 5ns to 9ns typical
• Operating temperature: 0°C to 70°C (commercial grade)

Applications

• Glue logic on vintage 8-bit and 16-bit computer boards - memory addressing, I/O selection
• Logic control boards in legacy industrial automation equipment
• Signal combining and pulse routing in timing circuits

Frequently Asked Questions

Is this compatible with 3.3V logic systems?

No. The DM74ALS32N requires a 5V supply (4.5V to 5.5V). It is not directly compatible with 3.3V logic without level shifters.

How does ALS compare to standard 74LS32?

ALS is faster (5-9ns vs. approximately 15ns for LS) and consumes less power than S-series. It is a drop-in functional equivalent in most 5V TTL designs, but verify timing margins if replacing LS in a timing-critical circuit.

Is this the original National Semiconductor part?

Yes. These are NOS chips sourced through surplus and legacy supplier channels - not modern reproductions or TI equivalents.

Is a datasheet available?

The DM74ALS32 datasheet was published by National Semiconductor and is available through Octopart, Fairchild archives, and similar component aggregators.
