The 20-SOIC (5.30mm body width) footprint is a standard JEDEC outline — no special pad geometry required for reflow assembly. ## ROHS3 compliance and supply posture ROHS3 compliant, the 74AC540SJ meets EU Directive 2015/863 without exemptions — no lead, mercury, cadmium, or phthalates in the package or plating.","metaTitle":"onsemi 74AC540SJ Buffer, Inverting, 3-State, 20-SOIC","metaDescription":"onsemi 74AC540SJ active buffer/inverter with 3-state output, 2V-6V supply, 24mA drive, -40°C to 85°C, 20-SOIC.
