Package
Applications
General Description
The TC4421A/TC4422A are improved versions of the
earlier TC4421/TC4422 family of single-output
MOSFET drivers. These devices are high-current
buffer/drivers capable of driving large MOSFETs and
Insulated Gate Bipolar Transistors (IGBTs). The
TC4421A/TC4422A have matched output rise and fall
times, as well as matched leading and falling-edge
propagation delay times. The TC4421A/TC4422A
devices also have very low cross-conduction current,
reducing the overall power dissipation of the device.
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 TC4421A/TC4422A 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, in addition to a wide operating temperature
range, the TC4421A/TC4422A family of 9A MOSFET
drivers fit into most any application where high gate/line
capacitance drive is required.
