156 / 186 page  ST10F280 156/186 Notes: 1. ST10F280 pins are equipped with low-noise output drivers which significantly improve the device’s EMI performance. These low-noise drivers deliver their maximum current only until the respective target output level is reached. After this, the output current is reduced. This results in increased impedance of the driver, which attenuates electrical noise from the connected PCB tracks. The current specified in column “Test Conditions” is delivered in any cases. 2. This specification is not valid for outputs which are switched to open drain mode. In this case the respective output will float and the voltage results from the external circuitry. 3. Partially tested, guaranteed by design characterization. 4. Overload conditions occur if the standard operating conditions are exceeded, i.e. the voltage on any pin exceeds the specified range (i.e. VOV > VDD+0.5V or VOV <0.5V). The absolute sum of input overload currents on all port pins may not exceed 50mA. The supply voltage must remain within the specified limits.
