Bus driver from the F/FAST family
The 54F240LM is a bus driver device from the F/FAST series, designed for high-speed digital bus interfacing in legacy logic systems.
RoHS non-compliance — a BOM flag
This part is RoHS non-compliant, meaning it contains lead (Pb) in the solder finish or internal construction. Designs requiring full RoHS-10 conformance (EU Directive 2011/65/EU) must use an alternative lead-free logic device. For legacy or military/aerospace assemblies that explicitly allow tin-lead solder, this is not a blocker.
Because it is a legacy F/FAST-series part, availability may vary by date code and region.
