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.
