No last-time-buy notice, no end-of-life window on the horizon.
Yes, at 1.8V VCC the input high threshold of 1.7V leaves about 100 mV of noise margin. The open-drain output can be pulled up to any voltage up to the absolute maximum of the output transistor (typically 2.7V), so it can drive a 1.8V input on the receiving side. Works fine for 1.8V systems as long as the input signal swing exceeds 1.7V.
