dized monolithic construction. The logic input is compatible with standard CMOS or LSTTL output, down to
3.3V logic. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-
conduction. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high side
configuration which operates up to 600 volts.

IR2181(4) (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.
