The 5401FM is a TTL NAND gate from Texas Instruments, part of the Logic ICs category. It implements the basic NAND logic function in the TTL (transistor-transistor logic) family, a standard for legacy and high-reliability digital systems.
Package and procurement context
Supplied in Bulk packaging, the 5401FM is a through-hole or surface-mount device depending on the specific package variant — the Bulk format typically indicates tubes or trays rather than tape-and-reel, which may affect your pick-and-place setup if you are running high-volume automated assembly.
