资 源 简 介
The TC4421M/TC4422M are high-current buffer/drivers capable of driving large MOSFETs and IGBTs.They are essenTIally immune to any form of upset,except direct overvoltage or over-dissipaTIon. Theycannot be latched, under any condiTIons, within theirpower and voltage raTIngs. These parts are not subjectto damage or improper operation when up to 5V ofground bounce is present on their ground terminals.They can accept, without damage or logic upset, morethan 1A inductive current of either polarity being forcedback into their outputs. In addition, all terminals are fullyprotected against up to 4 kV of electrostatic discharge.The TC4421M/TC4422M 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.
