The maximum voltage that can be applied to any source input pin is +60 V or -60 V, allowing the device to handle typical voltage fault conditions in industrial applications. Take caution: the device has different maximum stress ratings across different pin combinations and are defined as the following:
For example, if the device is powered by VDD supply of 25 V, then the maximum negative signal level on any source pin is –60 V. If the device is powered by VDD supply of 40 V, then the maximum negative signal level on any source pin is reduced to –45 V to maintain the 85 V maximum rating across the source pin and the supply.
For example, if the DR pin is left floating and an overvoltage voltage fault of –60 V occurs on the source pin S1, then the maximum positive voltage signal level driven on the drain pin channel D1 is 25 V to maintain the 85 V maximum rating across the source pin and the drain pin.
