No end-of-life notice or last-time-buy is in effect. The part is ROHS3 compliant. For new designs, this gate is a safe choice with no near-term obsolescence risk.
The CD74HCT11M has TTL-compatible input thresholds (low at 0.8V, high at 2V), while the CD74HC11M uses standard CMOS thresholds (low at 0.3 × VCC, high at 0.7 × VCC). In a 5V system, the HCT version will correctly interpret a 2.4V TTL high as a logic 1; the HC version may not. Choose HCT when driving from 5V TTL outputs; choose HC when driving from 5V CMOS outputs for better noise margin.
