i am looking at the 74LVC2G14. It is my go-to for buffering inputs. In 
the past i would use a dual shottky diode and limiting resistor as 
protection. But looking at the datasheet it seems the diodes are not 
needed. Also the current draw on an input is super low at 5uA. This 
means I can use a rather high value limiting resistor yes? This would 
simplify the design a bit.
