The 74FCT821ASPC is a bus driver from the FCT series, a logic family designed for high-speed bus-interface applications. It is a 10-bit D-type flip-flop with three-state outputs, commonly used in memory address buffering, data bus isolation, and control-signal distribution in microprocessor and digital systems. It is RoHS non-compliant, which means it contains lead and is exempt from RoHS restrictions for certain applications—verify your assembly line's lead-free requirements before committing the BOM.","metaTitle":"74FCT821ASPC FCT Bus Driver, Active, Bulk","metaDescription":"74FCT821ASPC is an FCT-series bus driver from the 74FCT family.
