What this TTL NAND gate is
The 5430FM is a TTL NAND gate — a basic logic building block for through-hole boards.
RoHS status and BOM fit
This part is RoHS non-compliant. If your assembly line runs lead-free solder profiles, the 5430FM will not pass without an exemption. For tin-lead (SnPb) processes — common in military, aerospace, or high-reliability rework — it is a direct drop-in. Verify your board's material declaration before committing the BOM line.
