Note

1. The additional quiescent supply current per input is determined by the ∆ICC unit load, which has to be multiplied by

the unit load coefficient as given in the individual data sheets. For dual supply systems the theoretical worst-case

(VI = 2.4 V; VCC = 5.5 V) specification is: ∆ICC = 0.65 mA (typical) and 1.8 mA (maximum) across temperature.
