8.3.7 Negative Clamping Diodes
The inputs and outputs to this device have negative clamping diodes as depicted in Figure 8-2.
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.
