(1) When VDD voltage falls below UVLO, reset is asserted for Output 1 and Output 2. VDD slew rate ≤ 100 mV / µs
(2) VPOR is the minimum VDD voltage for a controlled output state. Below VPOR, the output cannot be determined. VDD dv/dt ≤ 100mV/µs
(3) For adjustable voltage guidelines and resistor selection refer to Adjustable Voltage Thresholds in Application and Implementation section
(4) Hysteresis is with respect to VITP and VITN voltage threshold. VITP has negative hysteresis and VITN has positive hysteresis.
(5) For VOH and VOL relation to output variants refer to Timing Figures after the Timing Requirement Table
