CMOS technologies enable rugge-
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.

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.
