Quad 2-input NAND gate — 54F family logic
The 54F00FMQB is a quad 2-input NAND gate from the 54F series of high-speed bipolar logic. It packs four independent NAND gates into one package, each with two inputs, for general-purpose glue logic, gating, and inversion tasks in digital systems. The part is, typical for through-hole or large-quantity procurement. It is RoHS non-compliant, meaning it contains lead — a factor for designs that must meet RoHS directives or require lead-free solder processes.
Lifecycle and compliance
No end-of-life notice or last-time-buy window is in effect. RoHS non-compliant status means this part uses lead in its termination finish. For projects that require RoHS conformance, a lead-free alternative from the same logic family should be evaluated. The non-compliant status does not affect functionality or reliability for legacy or exempt applications.
