VDD is always higher than IN+ and IN− voltage. IN+ and IN− are allowed to have voltage range −0.05V to +2.35V when VDD = 2.7V and

|VID| / 2 to VDD − 0.3V when VDD = 3.0V to 3.6V. VID is not allowed to be greater than 100 mV when VCM = 0.05V to 2.35V when VDD =

2.7V or when VCM = |VID| / 2 to VDD − 0.3V when VDD = 3.0V to 3.6V.

(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.
