(1) Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground unless otherwise specified (such as VID).
(2) All typicals are given for: VDD = +3.3 V and TA = +25°C.
(3) VDD is always higher than IN+ and IN− voltage. IN+ and IN− are allowed to have voltage range −0.05 V to +2.35 V when VDD = 2.7 V and |VID| / 2 to VDD − 0.3 V when VDD = 3.0 V to 3.6 V. VID is not allowed to be greater than 100 mV when VCM = 0.05 V to 2.35 V when VDD = 2.7 V or when VCM = |VID| / 2 to VDD − 0.3 V when VDD = 3.0 V to 3.6 V.
(4) Output short-circuit current (IOS) is specified as magnitude only, minus sign indicates direction only. Only one output should be shorted at a time, do not exceed maximum junction temperature specification.
