Product details

Device identity and sourcing posture

The Texas Instruments 54LS09DMQB is an AND gate from the LS (Low-Power Schottky) series, a logic family that balances speed and power dissipation for TTL-based designs.

Military temperature range and the 54 vs 74 distinction

That wider thermal envelope is the deciding factor for avionics, missile-guidance, satellite, and downhole applications where the ambient exceeds the commercial limit.

RoHS status and compliance note

The 54LS09DMQB is a military-grade hermetic part from the era when RoHS exemptions for leaded solder and tin-lead finish were standard.

Frequently asked questions

What is the difference between 54LS09 and 74LS09?

The 54LS09DMQB also undergoes tighter screening and burn-in per MIL-STD-883 requirements.

What is the equivalent for 54LS09DMQB?

The peer SNJ54AS04J is a different logic function (inverter, not AND gate) and is not a functional substitute. For a pin-compatible AND gate in the same temperature grade, source the 54LS09DMQB directly against your BOM line.
