For new designs requiring RoHS compliance, a lead-free alternative from the 54S family or a functionally equivalent 74S-series part should be evaluated. As an active TTL device with a long production history, the 54S40DM is widely available through independent distribution.","metaTitle":"54S40DM Dual 4-Input NAND Gate, TTL, Active, Bulk","metaDescription":"54S40DM is a TTL NAND gate in Bulk packaging.

For a NAND-gate substitute, look at the 54S00 series (quad 2-input NAND) or the 54S10 series (triple 3-input NAND). The 54S40 itself is a dual 4-input NAND; no pin-compatible second source is listed in the manufacturer's cross-reference."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/54S40DM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/54S40DM when reusing this data.
