It packs four independent gates into a 14-SOIC surface-mount package, each gate accepting two inputs and driving a common open-collector node. The open-collector output is the key differentiator here — it lets you wire multiple gate outputs together to implement wired-OR logic, or shift the output voltage to a different rail by pulling up to a separate supply. Typical applications include bus-interface logic, level translation, and driving loads like LEDs or relays where a totem-pole output would conflict. The 74ALS family balances speed and power, making this a workhorse for 5 V industrial and commercial logic designs operating from 0°C to 70°C. ## Open collector — what it means for your circuit The SN74ALS03BD is rated for 8 mA sink on each output (low level). The 50 ns propagation delay at 5 V and 50 pF load is typical for the 74ALS family. ## Lifecycle and sourcing reality The SN74ALS03BD is listed as Active and ROHS3 compliant. For a BOM line that needs a standard 5 V NAND gate with open-collector outputs, this part is a straightforward fit.","metaTitle":"SN74ALS03BD TI 74ALS Quad 2-Input NAND Gate, Open Collector","metaDescription":"SN74ALS03BD is a TI 74ALS quad 2-input NAND gate with open-collector outputs, 4.5V-5.5V supply, 50ns propagation delay at 5V/50pF.

It is pin-compatible and functionally identical, but the ALS family offers faster propagation delay and lower power consumption. It is a drop-in replacement in most designs that can tolerate the faster edge rates."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ALS03BD","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ALS03BD when reusing this data.
