1. All voltage values are measured with respect to the ground pin.
2. P_diss is calculated with T_amb = 25°C, T_j = 150°C.
3. Attention must be paid to continuous power dissipation (V_DD x 250mA). Short-circuits can cause excessive
heating and destructive dissipation. Exposing the IC to a short-circuit for an extended period of time will
dramatically reduce the product’s life expectancy.

1. The minimum current consumption (I_STBY) is guaranteed at GND (TS488) or V_CC (TS489) for the whole
temperature range.
