GENERAL DESCRIPTION
The TC4426A/4427A/4428A are improved versions of
the earlier TC426/427/428 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 500 mA of reverse
current (of either polarity) being forced back into their
outputs. All terminals are fully protected against up to 4 kV
of electrostatic discharge.
As MOSFET drivers, the TC4426A/4427A/4428A can
easily switch 1000 pF gate capacitances in under 30 ns, 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.
