The logic input is com- patible 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.

Recommended Operating Conditions The input/output logic timing diagram is shown in Fig. 1. For proper operation the device should be used within the recommended conditions. The V and V offset rating are tested with all supplies biased at a 15 V differential. S SS Symbol Definition Min. Max.
