It packs four independent NAND gates into a single 14-SOIC package, each with two inputs. This is the standard logic building block for 5V TTL systems — glue logic, address decoding, control signal gating, and oscillator circuits in commercial-temperature equipment like bench instruments, office peripherals, and telecom line cards where the ambient stays below 70°C. ## Output drive — asymmetric, and that matters for fan-out The SN74LS00DR sources 400 µA and sinks 8 mA. That asymmetric drive is typical for LS TTL: the low-side sink is strong enough to drive about ten standard LS inputs, but the high-side source is weak. If you need to drive a heavier load — an LED, a relay coil, or a long trace — plan on a buffer transistor or a higher-drive gate like a 74F or 74ACT. The 8 mA sink is also the limiting factor if you parallel outputs to increase drive; the total package dissipation sets the real ceiling. ## Propagation delay — 15 ns at 5V, 15 pF Max propagation delay is 15 ns at 5V with 15 pF load. ## Package and rework — 14-SOIC, narrow body 14-SOIC package is 3.90 mm wide. ## Temperature grade — commercial only Operating temperature range is 0°C to 70°C. ## Lifecycle and sourcing reality The SN74LS00DR is listed as Active with ROHS3 compliance. No NRND flag, no last-time-buy notice. The 74LS family is mature but not dead — TI still runs these for legacy designs and repair stock.","metaTitle":"SN74LS00DR 74LS Quad 2-Input NAND Gate, 15 ns, 14-SOIC","metaDescription":"TI SN74LS00DR quad 2-input NAND gate, 74LS series. 4.75V–5.25V supply, 15 ns propagation delay, 400 µA/8 mA drive.

The SN74LS00DR is a bipolar TTL part limited to 4.75V–5.25V with asymmetric drive (400 µA source, 8 mA sink) versus the HC00's symmetric drive. The HC00 also has CMOS input thresholds (0.3xVCC low, 0.7xVCC high) instead of the LS00's fixed TTL levels (0.8V low, 2V high). They are not pin-compatible substitutes without checking the input threshold and drive requirements."},{"question":"Is SN74LS00DR RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74LS00DR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74LS00DR when reusing this data.
