Product details

The 54S15DM is an AND gate from the TTL/H/L series, designed for logic-level gating in digital circuits. It belongs to the 54S family, a high-speed Schottky TTL logic family that was widely used in industrial control, telecom, and military/aerospace systems through the 1980s and 1990s. The 'Bulk' package designation typically corresponds to a through-hole DIP format, making it a candidate for legacy board repair, MRO spares, or new builds that must maintain backward compatibility with existing socketed logic.

There is no NRND or EOL flag on this part. However, the RoHS compliance status is marked as non-compliant, which is typical for legacy TTL logic that uses lead-bearing solder finishes. If your assembly line is RoHS-exempt (military, aerospace, medical implant, or high-rel repair), this is not a blocker.

Sourcing reality for the 54S15DM

The 'Bulk' package means it ships in tubes or trays rather than tape-and-reel, so plan for manual pick-and-place or through-hole assembly. If you need a large production quantity, a lead-time check is advisable.

Frequently asked questions

Is 54S15DM the same as 74S15?

No, they are not the same. The 54S15DM is a 54-series AND gate with a military temperature range (-55°C to +125°C), while the 74S15 is a commercial-temperature (0°C to 70°C) part. Functionally they are identical, but the temperature grade differs.

Is 54S15DM RoHS compliant?

No, the 54S15DM is marked as RoHS non-compliant. This is typical for legacy TTL logic with lead-bearing solder finishes. If your application requires RoHS compliance, verify the finish or seek a waiver.
