Notes
1. All voltages are measured with respect to ground; positive currents flow into the chip; pin VCC may not be current
driven. The voltage ratings are valid provided other ratings are not violated; current ratings are valid provided the
maximum power rating is not violated.
2. Equivalent to discharging a 100 pF capacitor through a 1.5 kΩ series resistor.
3. Equivalent to discharging a 200 pF capacitor through a 0.75 µH coil and a 10 Ω resistor.
