Each gate sinks 5.2 mA per channel; the high side floats, requiring an external pull-up resistor. Supply range covers 2 V to 6 V, so it sits comfortably in a mixed-voltage BOM. The 17 ns propagation delay at 6 V, 50 pF is fast enough for most control and interface logic but not a contender for high-speed memory address decoding — that is not its job. The full military temperature range (-55°C to 125°C) qualifies it for avionics, downhole instrumentation, and outdoor telecom cabinets where the ambient can swing hard. ## Open drain means external pull-up — plan the resistor Rise time depends on the external pull-up resistor and load capacitance. Quiescent current is 2 µA. ## Active production, no end-of-life concern The CD74HC03M carries an Active lifecycle status and is ROHS3 compliant. No NRND flag or last-time-buy notice exists. ## Package and footprint — 14-SOIC, surface-mount only The part comes in a 14-SOIC package (3.90 mm body width, 0.154\" pitch) and is supplied in Tube — not Tape & Reel by default, so if your pick-and-place line expects reeled parts, factor in the tube-to-reel transfer or confirm the distributor can supply it on a reel. The mounting is surface-mount only; no through-hole variant exists in this order code.","metaTitle":"CD74HC03M 74HC Quad 2-Input NAND Gate, Open Drain, 14-SOIC","metaDescription":"CD74HC03M quad 2-input NAND gate with open-drain outputs, 2V-6V supply, -55°C to 125°C range.

The high-side driver is absent, so an external pull-up resistor is required for the output to reach a logic-high level."},{"question":"What is the difference between CD74HC03M and 74HC00?","answer":"The 74HC00 has standard totem-pole outputs that can both source and sink current. The CD74HC03M uses open-drain outputs — it can only sink current, and the high level is set by an external pull-up resistor. This makes the CD74HC03M the right choice for wired-OR connections and level translation, while the 74HC00 is better for driving standard CMOS inputs without an extra resistor."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HC03M","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HC03M when reusing this data.
