patible with standard CMOS or LSTTL output, down to 3.3 V 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 V.

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.
