8.3.3 Clamp Diode Structure

The inputs and outputs to this device have both positive and negative clamping diodes as depicted in #CLAMPDIODESIMG.

CAUTION:

Voltages beyond the values specified in the GUID-4854D19B-9DC3-4F29-8E22-0C3EA2F8F634.html#GUID-4854D19B-9DC3-4F29-8E22-0C3EA2F8F634 table can cause damage to the device. The recommended input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
