General Description
The TC1411/TC1411N are 1A CMOS buffer/drivers.
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 current
of either polarity being forced back into their output. All
terminals are fully protected against up to 4kV of
electrostatic discharge.
As MOSFET drivers, the TC1411/TC1411N can easily
charge a 1000pF gate capacitance in 25nsec with
matched rise and fall times, and provide low enough
impedance in both the ON and the OFF states to
ensure the MOSFET’s intended state will not be
affected, even by large transients. The rise and fall time
edges are matched to allow driving short-duration
inputs with greater accuracy.
