132 / 160 page  ST10F269 132/160 Notes: 1. ST10F269 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.
