(1) When VDD voltage falls below UVLO, OUT A and OUT B are asserted until VPOR. VDD slew rate ≤ 1V/µs
(2) VPOR is the minimum VDD voltage for a controlled output state. Below VPOR, the output cannot be determined. VDD slew rate ≤ 1V/µs
(3) Hysteresis is with respect to VITP and VITN voltage threshold. VITP has negative hysteresis and VITN has positive hysteresis.
