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.
