It performs the Boolean AND function on four inputs per gate, with two independent gates in one package. This is a logic gate for general-purpose combinatorial logic in systems that need a clean AND function without external inverters or multiple package counts. ## Lifecycle and sourcing reality The SNJ54HC21FK carries an active product status, meaning TI continues to manufacture and support this order code for new designs and production. ## Package and handling note The package itself is a ceramic leadless chip carrier (LCC) — the 'FK' suffix indicates a 20-terminal CQCC (ceramic quad flatpack) with J-bend leads, suitable for high-reliability and military-temperature-range applications where hermetic sealing is required.","metaTitle":"SNJ54HC21FK Dual 4-Input Positive-AND Gate, Active","metaDescription":"SNJ54HC21FK dual 4-input positive-AND gate in 54HC family.
