For designs requiring lead-free assembly or EU RoHS exemption compliance, this is a hard constraint — the part cannot be used in new products that must meet RoHS directives without an exemption. It remains suitable for repair, retrofit, and military/aerospace builds where leaded solder is still specified or exempted. ## Sourcing and lifecycle reality Because it is RoHS non-compliant, stock may be more common in non-RoHS inventory pools.","metaTitle":"CD74FCT646EN Octal Bus Transceiver, Active","metaDescription":"CD74FCT646EN octal bus transceiver from Texas Instruments.
