The maximum allowable supply ripple is 1% for 1 Hz to 5 kHz; 1.5% for 5 kHz to 10 MHz; 3% for 10 MHz to 100 MHz, and less than 5% for 100 MHz or greater. (2) The I2C pins SDA and SCL do not feature fail-safe I/O buffers. These pins could potentially draw current when the device is powered down. Due to the fact that different voltage devices can be connected to the I2C bus, the level of logic 0 (low) and logic 1 (high) are not fixed and depends on the associated VDD. (3) USB I/O pins DP and DN can tolerate a short circuit at D+ and D − to 0 V or 5 V, as long as the recommended series resistors (see Figure 5-40 ) are connected between the D+ and DP (package), and the D − and DN (package). Do not apply a short circuit to the USB I/O pins DP and DN in absence of the series resistors.
