Limiting values [1] Equivalent to discharging a 100 pF capacitor through a 1.5 k Ω series resistor. [2] Equivalent to discharging a 200 pF capacitor through a 0.75 μH coil and a 10 Ω resistor. 9. Thermal characteristics Table 3. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured with respect to ground (pin 2); positive currents flow into the chip. Voltage ratings are valid provided other ratings are not violated; current ratings are valid provided the other ratings are not violated.
