Quad NAND gate with open-drain outputs — what it means on the board
The CD74HCT03M: Operating temperature range is -55°C to 125°C. 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.
