Product details

What is the 74FCT821ASPC?

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.

Frequently asked questions

Is 74FCT821ASPC RoHS compliant?

No, the 74FCT821ASPC is RoHS non-compliant. It contains lead and is intended for applications where leaded solder is acceptable or exempt.

What is the equivalent replacement for 74FCT821ASPC?

No direct pin-for-pin replacement is listed in the manufacturer's cross-reference. For functional equivalents within the same logic family, consider the 74ACT16833DL (a 20-bit bus driver) or the SNJ54ALS574AFK (a military-grade octal D-type flip-flop), but verify pinout and timing compatibility before substitution.
