These devices 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 TC4421/TC4422 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.
With both surface-mount and pin-through-hole packages and four operating temperature range offerings, the TC4421/TC4422 family of 9A MOSFET drivers fits into any application where high gate/line capacitance drive is required.
