The SN74HC05NSR carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect. This part can be specified into a production BOM without near-term obsolescence risk.
The SN74HC05 has open-drain outputs; the SN74HC04 uses standard push-pull outputs. The HC05 can wire-OR multiple outputs or drive a higher-voltage pull-up rail, but requires an external pull-up resistor. The HC04 drives both high and low actively and needs no external resistor.
The SN74HCU04PWT is a functional alternative — it is also a hex inverter in a surface-mount package, but uses unbuffered (HCU) logic and push-pull outputs, not open-drain. For a direct open-drain replacement, stay with the SN74HC05 family.
Yes, the SN74HC05NSR is ROHS3 compliant, meaning it meets the EU RoHS directive for lead and other restricted substances.
