... Single Output On .............................................................420mA Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability ...

... SCLK’s falling edge. A rising edge at CS resets the output status register data. During normal operation, the output status bit is the same as the DIN bit (DO1 = D1, DO2 = D2). When the MAX4896 is operating with a fault condition, the output status bit is the inverse of the DIN bit (DO1 = 1). ...
