The device is marked RoHS non-compliant, so it contains lead (Pb) above the exemption threshold. For RoHS-required assemblies, a lead-free variant or an alternative bus switch from the same family would be needed — confirm your BOM's environmental requirements before committing. ## Sourcing and supply posture For high-volume or risk-mitigated builds, an RFQ can include a request for alternative bus switches with matching 20-pin SSOP/QSOP footprints and 5 V supply.","metaTitle":"74FST3244Q Renesas Bus Switch, 4 x 1:1, 20-SSOP, Active","metaDescription":"74FST3244Q Bus Switch from Renesas, 4 x 1:1 circuit, 4.75V-5.25V supply, -40°C to 85°C, 20-SSOP.
