General Description

The TC4421/TC4422 are high-current buffer/drivers

capable of driving large MOSFETs and IGBTs.

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 termi-

nals. 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 offer-

ings, the TC4421/22 family of 9A MOSFET drivers fit

into most any application where high gate/line

capacitance drive is required.
