The TC4428A 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. TC4428A 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 of TC4428A are fully protected against up to 4 kV of electrostatic discharge.

As MOSFET drivers, the TC4428A 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.
