Fully RoHS3 compliant, with no exemptions that would trigger a separate REACH or conflict-minerals filing for most OEMs.","metaTitle":"Renesas 74FCT244CTQG Buffer, Non-Inverting, 4-Bit, 5V","metaDescription":"Renesas 74FCT244CTQG buffer, non-inverting, 4-bit per element, 3-state outputs, 4.75V-5.25V supply, -40°C to 85°C, 20-QSOP.
