Packages 14-Lead PDIP IR21084 8-Lead SOIC IR2108S 8-Lead PDIP IR2108 14-Lead SOIC IR21084S Description The IR2108(4)(S) are high voltage, high speed power MOSFET and IGBT drivers with depen- dent high and low side referenced output channels. Proprietary HVIC and latch immune 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.
