is compatible 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.
