The 5430FMQB is a NAND gate logic device from the * series. It performs the fundamental NAND Boolean operation, used in glue logic, signal conditioning, and control interfaces across industrial, military, and aerospace systems where a through-hole package and leaded solder joints are specified.
Lifecycle and compliance reality
It is RoHS non-compliant, which is typical for leaded solder applications in high-reliability or legacy environments where exemption applies.
