Input Clamp Current, IIK
This is the maximum current that can flow safely into an input terminal of the device at voltages above or below the normal operating range.
Helpful Hint:
If there are clamp diodes between the device inputs and the VCC supply (see Figure 20), for ESD protection or overshoot clamping, there will be both a positive and negative absolute maximum rating for the input clamp current. If there is only a negative absolute maximum rating, that implies that there is only a ground-clamp diode at the input, not a power-clamp diode.
Output Clamp Current, IOK
This is the maximum current that can flow safely into an output terminal of the device at voltages above or below the normal operating range.
Helpful Hint:
If there are clamp diodes between the device outputs and the VCC supply (see Figure 20), for ESD protection or parasitic current paths in the output p-channel pullup transistor, there will be both a positive and a negative absolute-maximum rating for the output clamp current. If there is only a negative absolute-maximum rating, that implies that there is only a ground-clamp diode at the output, not a power-clamp diode or a parasitic current path in the output p-channel pullup transistor
