Each gate takes a single input. ## Commercial temperature range — indoor use only Rated 0°C to 70°C, this is a commercial-grade part. ## Sourcing and lifecycle TI lists the SN74ALS05AD as Active and ROHS3 compliant. For a BOM that needs a second-source hedge, the open-collector inverter function is common across the 74ALS family, but pin-for-pin replacement should be qualified against the specific pull-up and load conditions of your design.","metaTitle":"SN74ALS05AD 74ALS Hex Inverter, Open-Collector, 54ns","metaDescription":"TI SN74ALS05AD hex inverter with open-collector outputs. 54ns propagation delay at 5V, 50pF. 4.5V-5.5V supply, 0°C to 70°C.

That is the worst-case figure from the input crossing 2V to the output falling through 0.8V."},{"question":"Is SN74ALS05AD available in tube packaging?","answer":"Yes, the SN74ALS05AD is listed with a Tube package option. The device ships in a 14-SOIC surface-mount package."},{"question":"What are the alternatives to SN74ALS05AD?","answer":"A functional alternative within the 74ALS family is the SN74ALS11ANS, which is a triple 3-input AND gate — different logic function, same open-collector output structure. For a hex inverter with Schmitt-trigger inputs and wider temperature range, the SN74HCS04PWR covers -40°C to 125°C but uses a totem-pole output, not open-collector. The SN74F00DR is a quad 2-input NAND gate in the 74F family with 5 ns propagation delay, but again totem-pole output. None is a drop-in replacement; verify the output structure and pinout against your board."},{"question":"Can SN74ALS05AD be used as a buffer?","answer":"An inverter with open-collector output can be used as a buffer if you add an external pull-up resistor and accept the signal inversion — two inverters in series restore the polarity. But the intended use is wired-OR, level translation, or driving loads that require an open drain."},{"question":"Is SN74ALS05AD RoHS compliant?","answer":"Yes, the SN74ALS05AD is ROHS3 compliant."},{"question":"What is the difference between SN74ALS05A and SN74ALS05AD?","answer":"The 'D' suffix typically denotes the 14-SOIC package variant. The SN74ALS05AD is the surface-mount 14-SOIC version; the base SN74ALS05A without the D suffix is the through-hole DIP package. Electrical specifications are identical between the two."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ALS05AD","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ALS05AD when reusing this data.
