54F13FMQB — a 54F-series NAND gate in Bulk
The 54F13FMQB is a NAND gate from the 54F logic family. It is a basic logic building block used in systems that require positive-logic NAND functionality — think glue logic, address decoding, or control signal generation in industrial and military-grade equipment. The 54F series is known for its speed and compatibility with TTL levels, making this part a drop-in for legacy board repairs or new designs that need a through-hole logic gate.
Active lifecycle — still in production
However, note that it is RoHS non-compliant, so if your assembly line requires lead-free solder, you will need to verify exemption eligibility or plan for a separate handling flow.
Bulk packaging — what it tells you
That is typical for through-hole logic ICs intended for prototyping, repair benches, or low-volume production runs. If you are feeding a pick-and-place machine, you will need to transfer to a compatible carrier or look for a reeled variant — but for a bench repair or a small build, Bulk is exactly what you want.
