General Description  
• Driving the Largest MOSFETs and IGBTs  
• Local Power ON/OFF Switch  
• Motor and Solenoid Driver  
The TC4421/TC4422 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  
cannot 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 addition, all terminals are fully  
protected against up to 4kV of electrostatic discharge.

The TC4421/TC4422 inputs may be driven directly  
from either TTL or CMOS (3V to 18V). In addition,  
300mV of hysteresis is built into the input, providing  
noise immunity and allowing the device to be driven  
from slowly rising or falling waveforms.
