Open-collector means the output pulls low actively but floats high, so you wire an external pull-up resistor to whatever voltage the downstream logic or load needs, up to the transistor's breakdown limit. This makes the part a natural fit for driving relays, LEDs, or optocouplers from a 5 V logic rail, or for level-shifting a signal to a higher-voltage bus — the same open-drain topology used in I²C and many control lines. The 74LS family runs on 4.75 V to 5.25 V, so the input thresholds are TTL-compatible and the outputs can be pulled to 15 V or more depending on the external resistor and the transistor rating. ## Package and temperature grade for the BOM Housed in a 14-pin SOIC with 3.90 mm body width, the SN74LS07DR takes the standard narrow SOIC-14 footprint — 1.27 mm pitch, the same land pattern as a 74HC or 74HCT equivalent in the same package. The operating range is 0 °C to 70 °C ambient, which covers commercial and most indoor industrial environments but not automotive or extended-temp applications. Each of the six elements handles one bit, so a single package replaces six discrete open-collector transistors or a pair of smaller buffers. The -DR suffix indicates Tape & Reel packaging, also available as Cut Tape for prototype quantities.","metaTitle":"SN74LS07DR Texas Instruments Buffer, Open-Collector, 14-SOIC","metaDescription":"Texas Instruments SN74LS07DR hex buffer, non-inverting, open-collector outputs, 40mA sink per channel, 4.75-5.25V supply, 14-SOIC.

For a non-inverting open-collector buffer, the SN74LS07 is the correct choice. Within the same 74LS series, the SN74LS05 offers open-collector inverters, while the SN74LS34 provides non-inverting buffers with totem-pole outputs. No single pin-compatible drop-in exists that matches both the non-inverting logic and open-collector drive simultaneously across all manufacturers."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LS07DR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LS07DR when reusing this data.
