Product details

3-input TTL AND gate in the S series

The Texas Instruments SN74S11N is a 3-input AND gate from the S series of TTL logic devices. It performs the Boolean AND function on three inputs, delivering a high output only when all three inputs are high. This part is intended for through-hole assembly in legacy digital designs, prototyping, and rework of existing boards that use 5 V TTL logic levels.

Active lifecycle, but RoHS non-compliant

However, it is marked RoHS non-compliant, which is a critical distinction for any BOM requiring lead-free assembly per EU Directive 2011/65/EU. Designs that must meet RoHS compliance will need to evaluate a lead-free equivalent or accept the non-compliant status for exempt applications (e.g., certain military, aerospace, or medical sustainment programs).

Bulk packaging — what it means for procurement

This suits low-to-medium volume production runs, prototype builds, and repair stock. For high-volume automated insertion, verify that your pick-and-place or wave-solder feeder can handle tube-fed DIPs; otherwise, plan for manual placement or request a different packaging option if available.

Frequently asked questions

What is the difference between SN74S11N and SN74LS11N?

The SN74S11N is from the S series (Schottky TTL), which offers higher speed but higher power consumption compared to the LS series (Low-Power Schottky). The SN74LS11N would be the lower-power, slightly slower alternative. Both are 3-input AND gates in the same DIP pinout, but the S series typically has lower propagation delay at the cost of increased supply current. Exact parametric differences should be verified from the respective datasheets.
