Electrical Characteristics

Table 1. Absolute Maximum Ratings



Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may

adversely impact product reliability and result in failures not covered by warranty. Unless otherwise specified, all

voltages are measured with respect to SGND.
