The output can sink 5.2 mA but cannot source current — you must add an external pull-up resistor to VCC to get a logic-high level. That makes it useful for wired-OR busses, level translation (the pull-up can go to a different voltage than VCC), or driving loads like LEDs where you want the gate to sink current to ground. The -55°C to 125°C operating temperature puts it in the military-grade band — it survives cold-soak and engine-bay heat. Input logic thresholds scale with supply: low is 0.5V to 1.8V, high is 1.5V to 4.2V, so at 5V VCC a 3.3V CMOS output driving the input is marginal on the high side — check the actual driver's VOH against the 1.5V minimum. ## 17ns propagation delay — timing budget for medium-speed paths Maximum propagation delay is 17ns at 6V supply with a 50pF load. That gates the maximum toggle rate to roughly 30 MHz in a clean layout — fine for address decoding, chip-select generation, or status latching in a microcontroller system. For faster edges, the 74LVC family (like the SN74LVC2G132DCUR, which also has Schmitt-trigger inputs) offers 5ns at 5V, but at 1.65V minimum supply and only two gates per package. ## 2 µA quiescent current — static power is negligible The maximum quiescent supply current is 2 µA. In a battery-backed circuit that spends most of its time idle with the inputs held at a valid logic level, the gate's own draw rounds to zero on the system power budget. The open-drain output also means no shoot-through current when the output is low — the pull-up resistor's current is the only load.","metaTitle":"CD74HC03MT Texas Instruments 74HC NAND Gate, Open Drain","metaDescription":"Active-production 74HC quad 2-input NAND gate with open-drain outputs. 2V-6V supply, -55°C to 125°C. 17ns prop delay at 6V.

You must connect an external pull-up resistor from the output to VCC (or another voltage rail) to produce a logic-high level. This is useful for wired-OR connections, level shifting, or driving loads that sink current to ground."},{"question":"Will CD74HC03MT work at 3.3V?","answer":"Yes, the supply range is 2V to 6V, so 3.3V is well within spec. At 3.3V VCC, the input high threshold is 1.5V minimum, so a 3.3V CMOS output driving the input has margin. Propagation delay will be slightly longer than the 17ns figure quoted at 6V — expect roughly 25-30ns at 3.3V with a 50pF load."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HC03MT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HC03MT when reusing this data.
