Quiescent current is 2 µA maximum. ## Open-drain output — the sourcing angle The open-drain output sinks 4 mA rated and requires an external pull-up resistor for a logic high. The SN74ALS38BNSR uses an open-collector output with a 4.5 V supply but is limited to 0°C to 70°C and 33 ns propagation delay. ## Lifecycle and sourcing posture The CD74HCT03M is listed as Active with ROHS3 compliance. No NRND or last-time-buy notice exists.","metaTitle":"CD74HCT03M 74HCT Quad 2-Input NAND Gate, Open Drain, 14-SOIC","metaDescription":"CD74HCT03M quad 2-input NAND gate with open-drain outputs. 4.5V–5.5V supply, 24 ns delay, -55°C to 125°C.

The SN74ALS38BNSR is a similar open-collector NAND gate but has a commercial temperature range (0°C to 70°C) and slower propagation delay (33 ns), so it is not a pin-for-pin substitute for the full -55°C to 125°C range."},{"question":"What are the specs of CD74HCT03M?","answer":"It is a quad 2-input NAND gate with open-drain outputs, 4.5 V to 5.5 V supply, 2 µA quiescent current, 4 mA sink capability, 24 ns propagation delay at 4.5 V, 50 pF, and an operating temperature range of -55°C to 125°C. It comes in a 14-SOIC package."},{"question":"Is CD74HCT03M compatible with 5V logic?","answer":"Yes.
