Quiescent current is 2 µA maximum.
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.
No NRND or last-time-buy notice exists.
No, the CD74HCT03M is listed as Active with no end-of-life notice. It is still a viable choice for production and new designs.
There is no direct replacement listed. 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.
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.
Yes. The supply range is 4.5 V to 5.5 V, and the input logic thresholds (low at 0.8 V, high at 2 V) are directly compatible with 5 V CMOS and TTL outputs.
