Each gate sinks current on the low side; the high side requires an external pull-up. Supply range is 2V to 6V. Propagation delay is 17ns at 6V with a 50pF load. Temperature grade covers -55°C to 125°C, which puts it in the military/industrial bracket. If the board lives in an engine bay, a satellite, or a downhole tool, this gate handles the thermal swing. ## Lifecycle and sourcing The 74HC series is a mature logic family still in broad production, so this part remains a safe choice for both new designs and repair stock.","metaTitle":"CD74HC03E 74HC Quad 2-Input NAND Gate, Open Drain, 14-DIP","metaDescription":"CD74HC03E quad 2-input NAND gate with open-drain outputs. 2V–6V supply, -55°C to 125°C.

That means each output can only sink current; an external pull-up resistor is required for the high state."},{"question":"Can CD74HC03E replace a failed 74HC03?","answer":"Yes, the CD74HC03E is a standard 74HC03 quad NAND gate with open-drain outputs. It is a direct functional replacement for any 74HC03 in a 14-pin DIP package, provided the supply voltage and temperature range match the application."},{"question":"What is the difference between CD74HC03E and SN74HC03N?","answer":"Both are 74HC-series quad 2-input NAND gates with open-drain outputs in a 14-pin DIP package. The CD74HC03E is from Texas Instruments; the SN74HC03N is also a TI part. Electrically they are identical — same logic function, same supply range, same propagation delay. The difference is the manufacturer's ordering code and possibly the date code or factory origin. For a repair or a BOM line, either works as a drop-in."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HC03E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HC03E when reusing this data.
