Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to COM lead. 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 condition beyond those indicated in the “Recommended
Operating Conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may
affect device reliability. The thermal resistance and power dissipation ratings are measured under board mounted
and still air conditions. Ambient temperature (T A ) is 25°C, unless otherwise specified.

Recommended Operation Conditions
The input/output logic timing diagram is shown in Figure 1. For proper operation the device should be used within
the recommended conditions. The V S and V SS offset rating are tested with all supplies biased at 15 V differential.

Logic operational for V S of -5 V to +600 V. Logic state held for V S of -5 V to – V BS (Static).
Please refer to ‘Tolerability to Negative VS Transients’ section.
?? When V DD < 5 V, the minimum V SS offset is limited to –V DD .
