General Description
The TC4426A/TC4427A/TC4428A are improved
versions of the earlier TC426/TC427/TC428 family of
buffer/drivers (with which they are pin compatible).
They will not latch up under any conditions within their
power and voltage ratings. They are not subject to
damage when up to 5V of noise spiking (of either
polarity) occurs on the ground pin. They can accept,
without damage or logic upset, up to 500mA of reverse
current (of either polarity) being forced back into their
outputs. All terminals are fully protected against up to
4kV of electrostatic discharge.

As MOSFET drivers, the TC4426A/TC4427A/
TC4428A can easily switch 1000pF gate capacitances
in under 30nsec, and provide low enough impedances
in both the ON and OFF states to ensure the
MOSFET's intended state will not be affected, even by
large transients.
