It selects one of two 4-bit input buses onto a single 4-bit output bus based on a common select line. ## Lifecycle and sourcing reality The SN74AHCT158PW is listed as Active with ROHS3 compliance. The 74AHCT family is a mature logic series with broad distribution — this part is not exotic.","metaTitle":"SN74AHCT158PW 74AHCT Multiplexer, 4 x 2:1, 16-TSSOP","metaDescription":"SN74AHCT158PW 74AHCT multiplexer, 4 x 2:1 circuit, 4.5V-5.5V supply, -40°C to 85°C, 16-TSSOP.

In a 5V system with TTL drive, the AHCT version may switch more cleanly. Verify the input voltage thresholds against your driving logic before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74AHCT158PW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74AHCT158PW when reusing this data.
