gedized 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.
