This means the output can only sink current — it pulls low actively, but relies on an external pull-up resistor to go high. That makes it useful for wired-OR connections, level translation to a higher voltage rail, or driving loads like indicator LEDs where the high-side current path is handled off-chip. Each of the four gates sinks up to 64 mA per output when low, which is well above the typical 20 mA of a standard 74F00 gate. The propagation delay is 12.5 ns max at 5 V into a 50 pF load — fast enough for most glue-logic bus interfaces running at tens of megahertz, but the open-collector rise time depends on the pull-up resistor value and load capacitance, not just the gate itself. ## Supply, temperature, and package fit The quiescent supply current is 7 mA max, which is modest for a bipolar gate. Operating temperature is 0°C to 70°C, so this part is specified for commercial/indoor equipment, not extended industrial or automotive environments. The tube packaging means it ships in anti-static tubes, not tape-and-reel — a detail that matters if your pick-and-place feeder setup expects reeled parts. The footprint matches any generic SOIC-14 land pattern; no special thermal pad or exposed paddle to worry about.","metaTitle":"SN74F38D Texas Instruments 74F NAND Gate, Open Collector","metaDescription":"SN74F38D quad 2-input NAND gate with open-collector outputs.

The SN74F00DR can source and sink current (1 mA typical), while the SN74F38D only sinks (64 mA).

However, the SN74F38D's open-collector output requires an external pull-up resistor on each output to pull the line high — the SN74F00DR has a built-in totem-pole pull-up. If the original design relied on the totem-pole high drive, the SN74F38D will not drive the line high without the resistor."},{"question":"What compliance documentation does Texas Instruments provide for SN74F38D?","answer":"The part is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74F38D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74F38D when reusing this data.
