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 condition in industrial applications. Caution: the device has different maximum stress ratings across different pin combinations and are defined as the following:

1. Between source pins and supply rails: 85 V

   For example, if the device is powered by V_DD supply of 25 V, then the maximum negative signal level on any source pin is –60 V. If the device is powered by V_DD 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.

2. Between source pins and the same drain pins: 85 V

   For example, if channel S1 is ON and an overvoltage voltage fault of –60 V occurs on the source pin, 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.
