The 74F process gives it a propagation delay typical of the F series. The output drive is asymmetric: 1 mA source (high) and 24 mA sink (low). That 1 mA high-level drive is enough for CMOS logic inputs but will not drive a LED or relay directly — plan a buffer or pull-up if you need more source current. The 24 mA sink is generous for the low side; it can handle a standard TTL fan-out of ten loads without issue. It is intended for indoor, office, or consumer equipment where the ambient stays inside that range. The narrow SOIC footprint is common and matches the standard 16-SOIC land pattern. It ships in Tube. The ROHS3 compliance means it meets the latest EU RoHS directive without exemptions — no lead, no restricted phthalates.","metaTitle":"Texas Instruments SN74F151BD 74F Multiplexer, 1 x 8:1","metaDescription":"Texas Instruments SN74F151BD 74F series 1 x 8:1 multiplexer in 16-SOIC.

The 'B' suffix typically indicates a die revision or improved process within the 74F family. Functionally they are pin-compatible and interchangeable in most designs, but check the specific datasheet revision for any parametric differences in propagation delay or supply current."},{"question":"What is the cross reference for SN74F151BD?","answer":"The SN74F151BD is a standard 74F 8:1 multiplexer. Functional equivalents include the 74F151 in other packages (e.g., DIP) or the 74LS151 if speed is not critical. The SN74LS348N listed as a peer is a priority encoder (8:3), not a multiplexer — it is not a direct cross. For a drop-in replacement, stick with the same 74F151 in 16-SOIC from Texas Instruments or a licensed second source."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74F151BD","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74F151BD when reusing this data.
