8.3.7 Negative Clamping Diodes
The inputs and outputs to this device have negative clamping diodes as depicted in Figure 8-3.
CAUTION:
Voltages beyond the values specified in Section 6.1 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.
