Negative Clamping Diodes

The inputs and outputs to this device have negative clamping diodes as depicted in Figure 8.

CAUTION

Voltages beyond the values specified in the Absolute Maximum Ratings table can cause damage to the device. The input negative-voltage and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
