CMOS technologies enable ruggedized 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.
Symbol Definition Min. Max. Units
VB High side floating absolute voltage -0.3 625
Vs High side floating supply offset voltage VB - 25 " + 0.3
VH0 High side floating output voltage Vs - 0.3 VB + 0.3

Recommended Operating 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 vs and VSS offset rating are tested with all supplies biased at 15V differential.
