As it's for driving WS2812x I'd expect Vcc=5V and therefore it doesn't make a sense to use AHC version as it has pretty much the same input levels (CMOS) as WS2812
For the AHC version, that 3.3V...

AHCT - Advanced High speed Cmos - TTL switching levels compatible inputs.
TTL logic levels are: Log. 0 is between 0V to 0.8V and Log 1 is between 2V to 5V. So there is no problem with 3V3 CMOS...
