General Description

The TC4421/TC4422 are high-current buffer/drivers capable of driving large MOSFETs and IGBTs.

These devices are essentially immune to any form of upset, except direct overvoltage or over-dissipation. They cannot be latched under any conditions within their power and voltage ratings. These parts 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 damage or logic upset, more than 1A inductive current of either polarity being forced back into their outputs. In addition, all terminals

are fully protected against up to 4 kV of electrostatic discharge.
