VDD = 3.0 V, TA = -40 to 85 °C unless otherwise specified. 2. Data based on characterization results, not tested in production. 3. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization results, not tested. 4. The max. value may be exceeded if negative current is injected on adjacent pins. 5. Not tested in production. 6. RPU pull-up equivalent resistor based on a resistive transistor (corresponding IPU current characteristics described in Figure 22). 7. Data guaranteed by Design, not tested in production. |
