AD585 HOLD (logic) inputs

I want to tread the HOLD and /HOLD (true and complementary) inputs of an AD585 sample-and-hold amplifier as a differential pair, whose common-mode voltage is set by the LOGIC REF output. That seems to be the intention, as the datasheet says the reference output is 1.4V, the logic high is 2.0V and low is 0.8V. But this means wandering off the reservation a little bit; is what I'm proposing to do a valid use of these signals?
