Limiting values

[1]

Equivalent to discharging a 100 pF capacitor through a 1.5 k

Ω series resistor.

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. The voltage ratings are valid

provided other ratings are not violated; current ratings are valid provided the other ratings are not

violated.
