That is long enough for a typical linear regulator or a small DC-DC converter to reach steady state, but short enough that the system does not sit idle for a noticeable delay on power-up. If your design uses a slow-start supply or a large bulk capacitor, verify the ramp time does not exceed this window.
The part is RoHS non-compliant (contains lead).
Yes, the output is push-pull, totem pole, and active high.
Yes, the 2.19V threshold is designed to monitor a 2.5V rail, and the push-pull output drives 2.5V logic inputs directly.
