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. 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.
The TC4421M/TC4422M 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.
