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.
