GENERAL DESCRIPTION
capable of driving large MOSFETs and IGBTs.
except direct overvoltage or over-dissipation — they can-
not 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 addi-
tion, all terminals are fully protected against up to 4 kV of
electrostatic discharge.
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.
Part No.
The TC4421/4422 are high current buffer/drivers
They are essentially immune to any form of upset
The TC4421/4422 inputs may be driven directly from
