GENERAL DESCRIPTION

The TC4421/4422 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 — they can-

not be latched under any conditions within their power and

voltage ratings; they are not subject to damage or improper

operation when up to 5V of ground bounce is present on

their ground terminals; they can accept, without either

damage or logic upset, more than 1A inductive current of

either polarity being forced back into their outputs. In addi-

tion, all terminals are fully protected against up to 4 kV of

electrostatic discharge.

The TC4421/4422 inputs may be driven directly from

either TTL or CMOS (3V to 18V). In addition, 300 mV of

hysteresis is built into the input, providing noise immunity

and allowing the device to be driven from slowly rising or

falling waveforms.
