General Description
The TC4421/TC4422 are high current buffer/driverscapable
of driving large MOSFETs and IGBTs.
They are essentially immune to any form of upsetexcept
direct overvoltage or over-dissipation – theycannot
be latched under any conditions within theirpower
and voltage ratings; they are not subject todamage
or improper operation when up to 5V of groundbounce
is present on their ground terminals; they canaccept,
without either 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 4kV of electrostatic discharge.
The TC4421/TC4422 inputs may be driven directlyfrom
either TTL or CMOS (3V to 18V). In addition,300mV of
hysteresis is built into the input, providingnoise immunity
and allowing the device to be drivenfrom slowly rising
or falling waveforms.
