Device identity and active lifecycle
The 74ACTQ377SC is a D flip-flop from Texas Instruments' ACT series, a logic family that combines advanced CMOS (ACT) speed with TTL-compatible input thresholds. The part ships in Bulk packaging — loose tubes or trays suitable for bench-level prototyping, repair kitting, or low-volume production runs where tape-and-reel is not required.
Compliance and sourcing boundary
The 74ACTQ377SC is marked RoHS non-compliant (lead-bearing per the exemption structure in place at the time of manufacture). This is a critical filter for BOMs that require full RoHS 2/3 exemption-free compliance — the part is not suitable for new designs targeting RoHS-only assembly unless a leaded exemption (e.g., for high-reliability or exempted categories) applies. For projects requiring full material declaration or third-party certification, the buyer should confirm at RFQ whether TI provides a declaration of non-use or if a specific lot-level certificate is needed.
Because the part is Active and RoHS non-compliant, it occupies a narrow sourcing lane: it is not a standard stock item for most distributors who have moved to RoHS-compliant inventory, but it remains orderable from Texas Instruments through authorized channels. For a BOM that requires a drop-in replacement, the buyer would need to evaluate the entire ACT logic family for a RoHS-compliant variant with the same function and package — this is a parametric search, not a cross-reference.
