DC Characteristics
The following tables provide DC characteristics for operating conditions, inputs, and outputs.
Warning: The rise time of the 3.3v power supply must be between 700 mS and 140ms and the
inrush current must be limited to less than 2 A. A rise time outside of these limits may cause the
device to malfunction and give a 3-1-3 diagnostic error.
