4 ~ 5 us VSS/COM 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 crossconduction.
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.
