The 74ACT11027D is a 3-input NOR gate from the ACT series.
This part is RoHS non-compliant, containing lead in the solder finish or internal construction.
This is typical for through-hole or large-body DIP/SOIC parts intended for hand-assembly, prototyping, or low-volume production. If your line runs automated pick-and-place, factor in the extra handling step or request a tape-and-reel variant if one exists in the family.
No, it is marked RoHS non-compliant. The part contains lead and is not suitable for lead-free assembly without an applicable exemption.
The 74ACT11027D is from the ACT series, which has TTL-compatible input thresholds and higher drive capability compared to the HC series. The HC11027 uses standard CMOS thresholds and operates over a wider supply range. The ACT variant is a direct drop-in for TTL-logic systems without needing level translation.
A functional equivalent in the same logic family is the 74AC11004DW, but that is a hex inverter, not a 3-input NOR gate. For a direct NOR-gate replacement, look at other ACT-series 3-input NOR gates from TI or a second-source vendor. The pinout and function are standard for the 74ACT family.
