PIN CONFIGURATIONS
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
3 ^{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
4 ^{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.
