PRODUCTION DATA
The maximum voltage that can be applied to any source input pin is +60 V or -60 V, regardless of supply voltage. This allows the device to handle typical voltage fault conditions in industrial applications. It shall be cautioned that the device is rated to handle maximum stress of 85 V across different pins, such as the following:
For example, if the device is powered by VDD supply of 20 V, then the maximum negative signal level on any source pin is –60 V to maintain the 60 V maximum rating on any source pin. 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 channel S1(A) is ON and the voltage on S1(A) pin is 40 V. In this case, the drain voltage is also 40 V. The maximum negative voltage on any of the other source pins is –45 V to maintain the 85 V maximum rating across the source pin and the drain pin.
