Each gate accepts one input and, because the output transistor collector is left uncommitted, you can pull it up to a different voltage than the supply rail — or wire multiple outputs together for a wired-OR configuration. The 20 mA sink rating per output gives enough drive for small relays, indicator LEDs, or pulling down a bus line. Supply sits at 5 V nominal (4.75 V to 5.25 V range), and the 74S Schottky family delivers a 7.5 ns propagation delay at 5 V with a 50 pF load — fast enough for moderate-speed glue logic but not as power-hungry as the 74F series. ## Where it fits — and where it doesn't The 0°C to 70°C commercial temperature range limits this part to indoor, temperature-controlled equipment. The through-hole 14-DIP package is board-rewire friendly for prototypes and legacy PCB layouts. ## Lifecycle and sourcing The SN74S05N carries an Active lifecycle status from Texas Instruments. The ROHS3 compliance covers the latest environmental directives.","metaTitle":"SN74S05N Hex Inverter, Open Collector, 14-DIP, 74S Series","metaDescription":"SN74S05N — 6-channel open-collector inverter, 4.75V–5.25V supply, 7.5ns @ 5V/50pF.

No end-of-life notification has been issued. It remains a current-production part from Texas Instruments."},{"question":"SN74S05N vs SN74LS05N — what's the difference?","answer":"Both are hex open-collector inverters in the same pinout. The 74S version (SN74S05N) uses Schottky clamping for faster switching — 7.5 ns propagation delay at 5V/50pF — while the 74LS version is slower (about 15 ns) but draws less supply current. Choose 74S when timing margin is tight; choose 74LS for lower power in less speed-critical paths."},{"question":"What is a functional equivalent for SN74S05N?","answer":"The SN74LS05N is a direct pin-compatible alternative in the 74LS family with the same six open-collector inverters. For a surface-mount footprint, the SN74ALS38BNSR is a quad 2-input NAND with open-collector outputs — different logic function but same open-drain capability. No single exact second-source exists; the best fit depends on your logic function and package requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74S05N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74S05N when reusing this data.
