5 / 26 page  NOA3315W www.onsemi.com 5 Table 4. ELECTRICAL CHARACTERISTICS (Unless otherwise specified, these specifications apply over 2.3 V < VDD < 3.6 V, 1.7 V < VDD_I2C < 1.9 V, −40 °C < TA < 80°C, 10 pF < Cb < 100 pF) (See Note 4) Parameter Unit Max Typ Min Symbol Capacitive load for each bus line (including all parasitic capacitance) (Note 6) Cb 10 100 pF Noise margin at the low level (for each connected device − including hysteresis) VnL 0.1 VDD − V Noise margin at the high level (for each connected device − including hysteresis) VnH 0.2 VDD − V 4. Refer to Figure 2 and Figure 3 for more information on AC characteristics. 5. The rise time and fall time are dependent on both the bus capacitance (Cb) and the bus pull−up resistor Rp. Max and min pull−up resistor values are determined as follows: Rp(max) = tr (max)/(0.8473 x Cb) and Rp(min) = (Vdd_I2C – Vol(max))/Iol. 6. Cb = capacitance of one bus line, maximum value of which including all parasitic capacitances should be less than 100 pF. Bus capacitance up to 400 pF is supported, but at relaxed timing. Table 5.
