What are you driving? How fast? How big a load? The LVC07A is open 
drain, right? Do you need to source current too?

There are high-current "low-side FET" or relay drivers available in 1- 
and 2-driver packages. Some are overload protected.

Then there's the automotive P-FETs with current limiting, but these are 
probably much higher current than you need.

If you're looking at using an LVC07A, you should consider the 
single-gate "tiny logic" drivers.
