Need alternative to 74LVC2G14, with a lot less IDD current in analog mode

Hi I am using this one: Riding the input just between the lower and upper threshold. Problem is that the cross current (IDD to GND) is high (se figure 12) Anyone know of one that is equally fast, but with less current? Cheers Klaus

There are several Fairchild parts (designed by yours truly ;-), that aren't "renamed", that will do just fine. ...Jim Thompson

The advantage of a "comparator" here would be hysteresis and much lower guaranteed input offset. I don't think that LVDS receivers have hysteresis, or at least they don't mention it.

Ahem, again, we need names and part numbers.

Thanks Jim.

I'm working on something... you may have just sold some parts.

FIN1017 is a driver. Did you do the corresponding receivers too? Do any have hysteresis?

We use a lot of FIN1101, an lvds-lvds buffer, in unorthodox ways.
