Nice part, low power. I have a use for it already.

Don't get too excited, a lot of funny business with their spec sheet, espec ially where they test Tpd with 20K-ohm and 25pf load and list fall times an d Tpd,HL only. Of course, that load gets you a 1.1us 10-90% rise time, kiss your "LOW POWER" good bye if you need symmetrically fast performance on th e Tpd- I know that's highly unusual .

I really don't need it to be very fast, but the super low power and hysteresis are great.
