The TC4421/TC4422 are high-current buffer/driverscapable of driving large MOSFETs and IGBTs.These devices are essentially immune to any form ofupset, except direct overvoltage or over-dissipation.They cannot be latched under any conditions withintheir power and voltage ratings. These parts are notsubject to damage or improper operation when up to5V of ground bounce is present on their ground terminals.They can accept, without damage or logic upset,more than 1A inductive current of either polarity beingforced back into their outputs. In addition, all terminalsare fully protected against up to 4 kV of electrostaticdischarge.The TC4421/TC4422 inputs may be driven directlyfrom either TTL or CMOS (3V to 18V). In addition,300 mV of hysteresis is built into the input, providingnoise immunity and allowing the device to be drivenfrom slowly rising or falling waveforms.With both surface-mount and pin-through-holepackages and four operating temperature range offerings,the TC4421/22 family of 9A MOSFET drivers fitinto most any application where high gate/linecapacitance drive is required.
