IRS2181/IRS21814(S)PbF
Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-
eters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured
under board mounted and still air conditions.

Note 1: All supplies are fully tested at 25 V and an internal 20 V clamp exists for each supply.
Recommended Operating Conditions
The input/output logic timing diagram is shown in Fig. 1. For proper operation the device should be used within the
recommended conditions. The V and V
S
offset rating are tested with all supplies biased at a 15 V differential.
