High output current hex inverter in SMD capsule
You'll have better luck searching for what your after as a "inverting buffer" or "inverting line driver" or simply a "buffer" as many have an invert option.  They often come with 4,8,16,32 I/Os.

Texas Instruments has a few, I chose them at random though, there are plenty of companies that make such parts.  likely at whatever voltage/current/propagation delay you could want.
