For MAX834 and MAX835 start-up, the /OUT pin state is dependent on IN once VCC rises above the minimum operating voltage threshold (i.e. 2.5V). Once VCC rises above the minimum operating voltage, there is a 35us glitch immunity period to prevent any noise from asserting /OUT. The part will not assert /OUT until after this period. If IN>1.204V after the glitch immunity period, then /OUT will be pulled high. Otherwise, /OUT is pulled low.
