The RoHS non-compliant marking is the key constraint: this part contains lead (Pb) in the solder finish or die attach, which means it cannot be used in new EU RoHS-exempted designs without a specific exemption (e.g., for high-reliability or aerospace applications that still permit leaded solder). For BOM planning, factor in the need for a RoHS compliance statement or an explicit exemption waiver if your end-market requires it.","metaTitle":"7403DC TTL NAND Gate, Active, RoHS Non-Compliant","metaDescription":"7403DC is an active TTL NAND gate in Bulk packaging.

The open-collector version lets you tie multiple outputs together for wired-AND logic and drive loads at higher voltages than the standard 5 V rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/7403DC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/7403DC when reusing this data.
