Yeah I guess your right people do list all sorts of variations for this chip and a few others, but if you make sure what they are selling is what you want then should be ok, but if your not sure then you can always ask the seller for more details?
I have used the 74HC4514 and 74HCT4514 variations of this chip, I would recommend using the 74HCT4514 variation as this chip uses TTL inputs so works directly connected to your microchip, but if you find yourself with a 74HC4514 then this uses CMOS inputs, which makes it slightly more difficult when connecting it to a microchip.
For an example a CMOS Input to be a logic 1 state as to be at votage levels 3.5v or above, where as a TTL logic 1 state as to be at 2v or above to be a logic 1. ( check out the picture below )
So I have found to over come this issue we use a pull-up resistor connected on the data lines, this then helps to give us our 3.5v voltage levels. (Ive used a 1K pull-up resistor)
